This is caused by a bug which started affecting all released versions of Aqwa on 01/01/2022. The possible solutions are:

  • Update your Ansys installation to 2022 R1 Service Pack 1 or 2022 R2; or
  • Re-run your Aqwa analysis with 'Generate Wave Grid Pressures' option (in Aqwa Workbench editor), or with 'SEAG' data record (in Aqwa input file); or
  • If you have one, copy any old PAG file into your analysis directory and AqwaGS should automatically recreate it (this may take several minutes, during which time AqwaGS will be unresponsive).

I hope this helps.
