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.
