  dear all,
  
  I got following error and my simulation stops
  
  Node 999999: Process9270: Received signal SIGSEGV
  
  is anyone got this type error in Ansys fluent v16.2 when used in the parallel processor
  
  When I search for the error it shows data collection error through multiple processors
  
  how can we transfer all the data through MPI on the Main node where we can write all the data in fluent v16.2

  It's possibly a network glitch, are you running over several machines?

  I am using a single workstation
  
  And once I switch my simulation to the series mode it works fine but it takes a lot of time to complete one simulation

  Hello rwoolhou,
  
  The problem got solved with the Ansys fluent v18 I don't know how but I just thought to upgrade Ansys version and try. It got solved
  
  Simulations were running fine
  
  Thank you

  Are you using UDF's? Fluent tends to give this error if the UDF is not parallelized correctly.
