Hotfixes 2017

This hotfix resolves a problem in the MT module that could result in negative bed thickness and negative concentrations.

This MIKE HYDRO Basin Hotfix will prevent the .NET Interface in the MHB engine to allocate unnecessary memory when running a MHB setup including irrigation. This inefficient allocation produces the simulation to run slower each time step, when a simulation has been setup through the .net interface. The hotfix does not make any difference in simulations run directly from MIKE HYDRO.

This MIKE HYDRO Basin hotfix prevents an unexpected Exception during the call of the MikeBasin.Engine Api method: RememberFromHotStart(bool). The hotfix will allow to use the method in any .Net project using DHI.MikeBasin.Engine.dll, without this unexpected exception.

This hotfix corrects the error: “Chainage argument is outside span”. This may come up for routing branches with position of routing elements that coincides with tributary connections.

This hot-fix resolves internet license issues when working with MIKE C-MAP data files in MIKE Zero.

This hotfix fixes issues with PFS file handling in Coupled MIKE URBAN-MIKE SHE simulations on a server.

This hot-fix resolves license check issues with timeouts in MIKE URBAN.

This hot-fix resolves license check issues with timeouts in MIKE ZERO.

This hotfix resolves a problem in the ST module related to using the Meyer-Peter and Müller bed load formulation at small velocities.

The MIKE SHE Well Editor allows import of wells and filter definitions from a text file. Inconveniently it is not possible to have spaces in the imported text fields like the dfs0 file name. Also you cannot import filter definitions as “disabled” or “fixed pumping rate”. This will be enabled by this hot fix. For a disabled filter set the “item number” field to a negative value, for a constant pumping rate set it to 0 and specify the actual rate instead of a time series dfs0 file name.

This Mike Hydro hotfix allows to run a Rain Fall Run Off – Mike Hydro Basin simulation with res1d hotstart files. The software was currently ignoring the hotstart file and this hotfix corrects the issue.

This hotfix resolves an issue where a right-click with the mouse in the graphical view of the Grid Series Editor would cause the context menu to appear multiple times.

This hotfix reduces computer memory consumption during MIKE 1D LTS simulations.

This hotfix resolves a possible issue concerning the visualization and editing of large data files in the Grid Editor.

This hotfix resolves two issues with RDI calculations: If RR simulation is RDI (solo) and RdiiNo is set to false (zero) to skip RDI calculations for that catchment, also Catchment Discharge calculations was skipped. If RDI area is zero, NaN numbers was produced and the RR result file would not work for network calculations.

This hotfix resolves round-off issue that triggers “index-out-of-bounds” error for UHM catchments.

This MIKE HYDRO hotfix corrects the cross-section data sent to MIKE SHE in a MIKE SHE-River coupled simulation. With this corrected data, MIKE SHE gets a more precise information about the river bed levels, including all cross-section table points. It also makes the river simulation create a water balance report file as well as an error log file. Both file in html format. The water balance contains information of the water volume exchanged between MIKE HYDRO and MIKE SHE, from the MIKE HYDRO point of view.

This fix resolves issues with properly viewing MIKE 1D LTS *.ERF results in MIKE View.

This hotfix makes the Advection-dispersion exchange of MIKE FLOOD models using Mike1D engine, to be triggered on upon check box flag of the couple file (“Apply AD-coupling”). This means ignoring any internal parameter in the couple file that it is currently considered.

The hotfix also disables the dispersion modelling at all water level boundary coupling links (standard link, side structure links, urban/river links). This change makes the concentrations to move only in the direction of the HD coupling exchange for boundary value coupling links, which is the expecting behavior of water level boundary coupling links.

This hotfix resolves the problem that the GPU version of MIKE 21 FM or MIKE 3 FM could fail and stop when more than 1 subdomain was used in combination with gate structures and “water level” or “water level difference” is used for operation.

This hotfix resolves a mismatch where engine establishes simulation time in seconds, and file time in hours, which may lead to a ‘Data does not cover entire simulation’ validation error.

This hotfix corrects the exchange in urban-river links, which was failing to produce exchange discharge for non AD links.

This hotfix resolves issues with LTS job list file generation, and the processing of large job list files for LTS simulations with the MIKE 1D engine.

This hotfix resolves an issue, so that derived result items from MIKE 1D like link flood and link depth, are now showed correctly in MIKE View.

This hotfix resolves an issue, so that derived result items from MIKE 1D like link flood and link depth, are now showed correctly in MIKE View.

The MIKE SHE preprocessor selected the wrong output location for detailed river time series output (H/Q) in many cases. When this happened the output was correct for the location given in the PP-print log file, but this was not the location specified by the user, or the closest available calculation point. With this hotfix the correct point is selected again, preferring the closest calculation point in the same river segment. For additional information the message “WARNING: Invalid chainage of branch [...]” will now also contain the actual distance between specified and adjusted chainage. Also, if the adjusted chainage is outside the branch segment bounds (allowing a small tolerance), an error message will be printed.

This hot-fix resolves license issues with special combination of license modules in the license file (pending license modules + additional license modules for different products or with different limitations).

This MIKE HYDRO River hotfix corrects an error in the Data Assimilation module. When updating with weighting function, the value of an equation parameter was wrongly rounded during the simulation.

This MIKE HYDRO Basin hotfix corrects the formula in the Irrigation module. The correction constrains the soil moisture reduction factor to a minimum value of zero to prevent negative values when the root zone depletion exceeds the wilting point depletion.

MIKE URBAN geometric network rebuild has been fixed to work accordingly in silent mode, allowing to continue the process regardless of the warnings issued for the Net_Builder when importing data.

This Hotfix fixes the runtime error of MIKE FLOOD models with Urban-River links failing to run without a valid reason and giving an incomplete run-time error message “(Unexpected error defining urban-river link number: XXX, urban link ID: YYY. Details: La référence d'objet n'est pas définie à une instance d'un objet.)

The error is an engine error and it is therefore corrected and the model should run without any error.

This hotfix is a temporary solution to address the dongle issue with Window 10 April 2018 Update, Version 1803. Users using this hotfix may experience MIKE software recognizing their system as windows 8. A permanent solution will be issued after we have solved it with our partners.

This hotfix include a correction of bed boundary condition for the K-epsilon equations for the case where the ratio between the roughness and bottom layer thickness become large.

This hotfix addresses a problem in the MIKE SHE grid calculator tool. It was failing with the message “The parameter is not valid” when run from the GUI.

The current MIKE FLOOD hotfix corrects the calculation of the external levee data for lateral links in Flood models, when the levee data is input as text file. The data is expected to replace the data from the river model, but failed to do so. The hotfix also corrects the  plotting  of the output crest level cross section file ‘M1DLateralCrestLevel.xns11’ for the same type of input.

This hotfix resolves a read-in problem of pier data in the ‘classic’ MIKE 21 Flow Model.

This hotfix addresses a problem with the Send Data Tool “MOUSEtoSWMM”, in which pipes with CRS sections were exported to SWMM as CIRCULAR shaped pipes. These pipes now are properly exported as Irregular Shape with its corresponding geometry curve.

This hotfix resolves an issue when Colebrook-White friction formulation is used in an LTS simulation, when producing the ERF result file.

This hot-fix resolves license issues with MIKE Zero Data Viewer and MIKE Zero Data Manager.

This hotfix is enables the following:

-       Forces the storage demand rule releases to be routed through hydropower plants, when the two involved reservoirs are physically connected

-       Make all Reservoir releases routed through hydropower plants as default behavior. Spill is only considered if the water is released due to surpassing the damn crest level, or the flood control release that does NOT go through Hydropower plant.

(Note: this hotfix is an improved version and replaces a former hotfix MIKE_Zero_2017_18.01.29.exe.)

This hot-fix resolves license check issues in MIKE URBAN.

This hotfix solves an issue related to weirs and culverts in MIKE 3 FM and MIKE 3 Coupled Model FM that could prevent the model from running.

This hot-fix resolves license issues with MIKE Zero Data Manager.

This hotfix resolves an issue in the MT module occurring by very high fall velocities that in turn could result in negative bed thickness and excess concentrations.

This hotfix allows corrects the enforcing of the maximum allowed downstream release of a Reservoir in the context of the Global ranking allocation algorithm. To account for the maximum release it considers the releases downstream and down releases redirected to a connected hydropower.

This hot-fix resolves issues with GPU simulations in remote simulation on HW with two or more GPU cards. It should be installed on servers running remote simulation services (Remote Simulation Server Components) for MIKE Zero.

This hotfix addresses two issues.

 1) A performance problem has been fixed, occurring when a large number of structures are present in the simulation and the simulation is using a hotstart file for initial conditions.
 2) HTML summary reports incorrectly a too high loss (infiltration) for catchments of type Model B (Kinematic Wave).

This hotfix addresses the possibility to export longitudinal profiles to *.dxg-file format allowing the use of multiple layers to store different data presented in the profile.

This hotfix solves a problem with importing SWMM models from an *.inp-file in which the geometry of some links is defined as polylines leading to multiple coordinates for the same geometric definition of the link.

This hotfix addresses a problem with fire flow computation when using “Calculate available flow for design pressure” not writing correct results to the *.ffa-file.

This hotfix addresses a situation with the Calibration Plots and Reports tool in which for WD results the result item “Link Flow” was not recognized by the tool.

This hotfix resolves two issues relating to MIKE 3 FM:

- error using radiation stress in the 3D GPU version

- problem using line structures (weirs, culverts, gates or dikes) in combination with Non Equilibrium Pure current transport description in the ST module

This MIKE HYDRO Basin hotfix routes the global ranking reservoir releases through the Hydro-Power plants, when the corresponding checkbox in the individual hydropower properties is checked. At the same time reports the flood control releases as spill release.

This hotfix resolves an issue in Data Assimilation where observation measurements are compared to the wrong simulation values, thus ending up with unexpected modifications. This only happens in models using multiple types of observations and if these observations are not sorted properly.

This hotfix corrects two current defects. First, a crash that happens if the user tries to set the coordinate system to GCS_WGS_1984, and second: the impossibility to import polylines into a branch set in MIKE HYDRO Import from shape file tool.

This MIKE HYDRO Basin hotfix prevents delete values of concentrations to propagate downstream in the basin network. Therefore a zero-upstream contribution is included for these reaches, and a warning is issued in the log file. It also increase the maximum number of warnings from the current value of 100 to an extended value of 5000, which is more realistic for large models. Finally, the hotfix also includes a new result item, namely the reach storage, which is part of the reaches that have a routing method within the reach.

This hotfix resolves an issue with random characters saved in new Plot Composer setup files (.plc) which prevented the file to re-open in MIKE Zero.

The present hotfix corrects the use of the minimum release and regular reservoir releases into the Power plant water user, if one exists, this in the context of Global Ranking allocation. Therefore any reservoir release could be used for the generation of hydropower, as long as it respects the power generation capacity of the plant.

This hotfix improves the handling of importing SWMM (.inp files) models containing previously conflicting time patterns.

The DHI Internet License Service has been updated. If you are using an Internet license you need to install this hotfix.

This hotfix removes the dependency of Data type when using dfs0 files in the MIKE 21 tool ‘Tidal Analysis of Heights'.

This hotfix addresses a problem with multiplying the scaling factor to the agent pollutant concentrations while diluting with water inflows coming from cyclic profiles during MIKE 1D Advection-Dispersion (AD) modelling.

This hotfix relates to the Mooring Analysis module. It corrects an error in the interpolation for directions around 0 and some drag curves have been updated to ensure consistency.

Furthermore some fender curves have been updated to avoid strange behaviour in cases of small compression.

This hotfix resolves issues relating to using pipe roughness calibration.

The present hotfix corrects the calculation of the residence time in water quality basin networks using any water level method such as "manning", "from routing", or "rating curve". These water level methods are used to compute the water levels and this hotfix set the specified local or global parameters of the basin network, allowing the correct calculation of the residence time.

This hotfix corrects coupling issues which sometimes occur in lateral links and side structure links, preventing from starting the simulation. This hotfix is relevant only when the river model is built in MIKE HYDRO River, or when using the MIKE 1D engine in MIKE 11.

This hotfix corrects a rounding error of cross sections chainages, when cross sections are saved from MIKE HYDRO River or from the new cross section editor. This error caused the cross sections to be very slightly moved along branches, which can lead to cross sections being excluded from lateral links when using MIKE FLOOD, and in case cross sections have been defined at the exact ends of lateral links.

This hotfix corrects the calculation of the residence time for routing branches, which failed to be computed when a routing branch contained internal computational nodes.

This hotfix corrects an error in the computation of the connecting digipoints of two branches of a MIKE SHE coupling setup. The computation was assuming that the connecting node in the branch will have a format like “name,chainage”, which is not always the case and now this is corrected. This hotfix also corrects the calculation of the coupling point in a urban/river link in MIKE FLOOD, which might be faulty if the coupling branch contains a confluent branch or bifurcation.

This hotfix resolves an issue in the ‘Tidal Analysis of Currents’ tool when trying to analyse currents from a dfs2 file.

This hotfix enables customers to properly export information to MOUSE Project file type (.mpr). When a MOUSE project file (.mpr) is created two complementary files are also created one regarding hydrology information (.hgf) and one containing the network information (.und). This exporting capacity enhances communication for external data handling workflows.

This hotfix resolves an issue with jet sources in strong opposing flows.

This hotfix solves an issue when using the “change in sensor value” for the MIKE 1D engine.

This hotfix corrects the display of the result plotting option when selecting a model element in the map view after the simulation execution. This display option was not being showed for all model elements and the hotfix corrects this problem.

The Hotfix also corrects the lack of persistence in the display of the chosen background map after running a Mike Hydro River simulation. So, whatever background map is chosen, it is also displayed when user switches to the “results” tab.

This hotfix resolves an error introduced in Release 2017 regarding reading spatially distributed hydrodynamic conditions (dfs1) into the Coastline Evolution model.

This hot-fix resolves DHI License Manager issues that occurs when users are running two or more MIKE Zero instances on their PCs.
