Multipaction Simulation Exit Code -99

    • fabian.geissler

      Hi, I am trying to perform a multipaction simulation in HFSS under AEDT 2022R2. For some simulation frequencies the simulation is killed right after start with the error message: "Solving Multipaction1, power = 10, process hf3d exited with code -99. (5:10:37 PM  Aug 18, 2022)".

      What does exit code -99 mean? How can I prevent this from happening?

      I am a bit lost here as there is no real clue to what the problem is. Is there a way to get more details about what exactly caused the problem?

      Best regards,

      Hi Fabian,

      It is difficult to diagnose without looking at your model setup which we can not do in this forum. To start have you followed the Multipaction setup as per our free AIC course on Multipaction?  Here is the link:
