Got a problem with “mpt_accept: error: accept failed: No such file or directory”

  Everything is going well until I click "Calculate", this message keeps popping out "999999: mpt_accept: error: accept failed: No such file or directory".
  
  I have activated VOF, species and solidification models. The UDFs compiled with no error.
  
  After I did not use these UDFs, the simulation can run with several steps (even though it is diverging finally but at least the simulation can be started).
  
  hope anyone can help me with that.
  
  Thanks!

  The mpt error is generally associated with parallel, can you relaunch Fluent in serial and see what happens? There may also be another message in the TUI just above the one you mention: that can be more diagnostic.

  OK, run through the UDF and check everything is defined and/or given a value. I think you've missed a definition somewhere (and no, I'm not going to debug the code!).

  I too have the same error in Fluent. Did you find a way out for that error? If so please let me know, it will be helpful for me.
