MIKE Zero hotfix 13-07-2018

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

MIKE URBAN hotfix 10-07-2018

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.

MIKE URBAN hotfix 09-07-2018

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

MIKE HYDRO hotfix 22-06-2018

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.

MIKE URBAN hotfix 18-06-2018

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

MIKE FLOOD hotfix 13-06-2018

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.

MIKE FM hotfix 13-06-2018

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.

MIKE 21C hotfix 08-06-2018

MIKE FLOOD hotfix 04-06-2018

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

MIKE URBAN hotfix 04-06-2018

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.

MIKE URBAN hotfix 31-05-2018

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.

MIKE Zero hotfix 31-05-2018

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.

MIKE SHE hotfix 31-05-2018

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.

DHI License Manager hotfix 29-05-2018
