Hi, I recently upgraded my PC from 64 GB RAM to 192 GB and reinstalled Windows and ANSYS (2021 R2), and I was having issue running some old simulation files. Q3D simulation has been working fine, but whenever I do HFSS I get a notification of <\/p>\n

“SN015_p2 (C:\/KZ\/)
  ___SN015_res_cap_coupling (Modal Network)
    [error] Solving frequencies for broadband adaptive meshing … (Nondomain solver), process hf3d exited with code 259. (7:40:46 PM  Apr 16, 2024)
    [error] Simulation completed with execution error on server: Local Machine. (7:41:07 PM  Apr 16, 2024)
“<\/p>\n

I was trying to simulate some microwave transmission lines with perfect E boundary conditions, and it has worked well before. There are 3 properly defined lumped ports and I was simulating at the eigenmode frequencies I got from doing HFSS eigenmode analysis. I have appeneded a frequency sweep (interpolating) from 4 to 10 GHz to the solution setup. The HPC options are set to default. Sometimes I run into errors with HFSS eigenmode as well on designs I used to be able to simulate before, but for eigenmode, running the analysis again solves the issue. For modal analysis, I will get the same error message no matter how many times I run the same simulation. <\/p>\n

I have tried the following attempts to fix the issue and none of them worked:<\/p>\n

    \n
  1. Switching to terminal HFSS simulation<\/li>\n
  2. Changing the threshold for convergence<\/li>\n
  3. Uninstalling and reinstalling ANSYS<\/li>\n
  4. Made sure no special characters are in the file name<\/li>\n
  5. Deleting saved results.<\/li>\n
  6. Changing the TEMP file directory<\/li>\n<\/ol>\n

     <\/p>\n
