I am trying to simulate cardiovascular flow in parallel. But my program got stuck in the middle. Also, not provide any error messages.
Can anyone help me with this issue?

Re: Trouble in running in parallel ./svFSI
Hello Pratik Mitra,
What do you mean by my program got stuck in the middle ?
Do you mean that svFSI crashed? Did the job create any .bin or .vtu files?
The histor.dat file you included seems to show that svFSI did not start, should see something like
Cheers,
Dave

Dear Dave,
Thank you for your quick reply.
When I am running this code, my last message is printed in the history.dat file is;
Maybe it was able to read the grid but failed to start the "" and
Do you have any suggestions, on how to proceed.
Thank you,

Hello Pratik mitra,
You should make sure your simulation is setup correctly, run it from an sdev terminal.

Dave
