Ansys AQWA is not generating .AH1 file

  Hello all
  We have a system of WECs and other bodies that we are trying to solve the diffraction problem with. One of the people in our lab can run Aqwa and get the AH1 file to generate without issue, but when I run the simulation I can't. It generates a .LIS and a .hyd file, but isn't generating the .AH1 file. When he runs his workbench file it generates, but when I run that file, it doesn't, despite being the same file. Our versions should be the same as well. Does anyone have any ideas why this could be?
  Thanks

  Hi, to output the .AH1file, in AqwaWorkbench, you need to turn on ASCII Hydrodynamic Database option in the Analysis settings of Hydrodynamic Response.

  Even with that option on it is not outputing. That's why I'm confused.

  Hi, you can check if the AHD1 option is in the .DAT file. If it is in the DAT file, you can check if there are any error messages in the *.LIS and *.MES file. Try rebuilding the project could be another attempt. We don't have any bug records of .AH1 file generation failure.
