  Hi,
  
  I am trying to run an EM simulation in HFSS and the simulation runs fine when I use a lumped port in Driven Modal type. When I change the solution type to Driven Terminal and also change the settings of lumped port accordingly, the simulation fails. Also when I make a simple change in my 3D model, the Driven Modal type simulation is also failing.
  
  The error I am getting is as below:
  
  [error] Communication failure. System error no: 109, error description:Unknown error
  
  [error] Communication failure. System error no: 0, error description:No error
  
  [error] Solving adaptive frequency ..., process hf3d exited with code -1073741819.
  
  [error] Communication failure. System error no: 232, error description:Unknown error
  
  [error] Simulation completed with execution error on server: Local Machine.
  
  I have tried looking online but couldn't get much help on the exit code. Can someone help me understand what does this error mean ?

  I'm also encountering the same problem for a 2-D array of antennas. Anyone knows the solution or some other EDA forum where I can find the solution of this problem?

  Hi,
  
  I solved it by run program as administrator.
