  Check the messages when the UDF was compiled for errors. Then check you've got write access to all of the nodes & host.
  
  The number isn't overly useful, the message suggests a node-host data issue but could also be permissions related.
  
  If you try a case without any UDFs does that work?

  I have similar problem using fluent. And my spatial discretization is Green-Gauss Node Based. But when I tried to solve the problem I get the same error 999999 mpt_accept error accept failed.
  
  What do you mean my node host and permission related issue?

  The OP is using a UDF, if the nodes can't see the folders this can fail. It could be something else, hence the request to run a different case to confirm.
  
  There should also be another issue. What else did you see in the TUI, usually the mpt error follows something more diagnostic.
