      Hello Ansys Community - 

      Has anyone ever experience this error from HFSS 3D Layout (AED 2023 R2)?

      [error] Solving adaptive frequency ..., process hf3d exited with code -1073740791. (11:34:12 PM  May 10, 2024)
      [error] Solving adaptive passes failed. (11:34:32 PM  May 10, 2024)
      [error] EnsComEngine returned an error code. Please contact Ansys technical support. (11:34:33 PM  May 10, 2024)

      The profile shows 4 completed passes (unconverged) with 6 more tries to go.  Could this be a RAM issue?

      Best,

      Alex A.

      Hi Alex,

      Thanks for asking your question in Ansys Learning Forum. Can you please check the profile of the simulation for further details? If it is a memory related issue, you can read that from the Profile tab of the active window as shown above.
