Floating point exception (core dumped) in icoFsiFoam
1 Attachment(s)
Hello everyone,
I am trying to run a simulation for flow in a 3Dpipe using icoFsiFoam solver. The simulation runs for a few time step and then I get the following error: Floating point exception (core dumped)
Here are the last few lines from the log file

I am attaching the complete log file. Can anyone help? |
