G3dMesher Error on HPC

  Hello everyone,
  
  i'm trying to run a 3D EddyCurrent simulation on a Cluster which is Linux based. For some models i'm getting this error:
  [error] Unable to obtain process status for process G3dMesher
  
  As far as i know this error means, that the Engine lost the connection to the Mesher, although there is some mesh. I know that because in the beginning of the log-file the meshing process is listed and correct. The model works fine on a local machine (Win10). I had this error before with a other simulation model. Back then i changed a various parameter (some dimension of one body) and then all of a sudden it worked. Even when i changed the parameter to it's original value it worked. So i couldn't figure out the root cause of the problem. Now this error message appears again and i couldn't solve it yet. I also changed the Temp directory in the General Options to the project path.Then i tried to delete some bodies to see if the error is caused by some geometry. Maybe some of you had a similar problem and has a idea what could cause this error. Thanks a lot!

  Hello again
  
  meanwhile i could find the root cause. I didn't mention that i am using User-Defined-Primitives. The G3dMesher Error occurs once a UDP is in the model (even when it is declared as Non-Model!). With the help of the support we found out that this is a bug which was fixed with the 2020R1 Version. Currently my Cluster runs on 2019R3, but this will now be updated soon. I thought maybe this information could help someone else.
  
  Best regards
