  Hi,
  One of my simulations stopped with the erro message:
  (dpm/src/[email protected]): communication of "" of dimension 0 not handled.
  Error at Node 6: unknown dimension (0) for storage variable
  
  It means false parameter?or input wert uncompatblewith geometry?or something else.Inever met this before...
  
  Kind regards

  What are you doing with the code? Are there any UDFs?
