Hi,
I'm running SimVascular version 2023.3.27 with svFSI version 2023.5.25 using Ubuntu 20 on VirtualBox with OpenMPI. I'm following along with the cylinder tutorial in https://www.youtube.com/watch?v=N4AIL-z ... WL&index=1. After creating the input file and trying to run the simulation, I get the following error message:

[MAIN] cm.id: 0
Program received signal SIGILL: Illegal instruction.
Backtrace for this error:

Please advise.
Thank you,

Hi Moses,

It's not clear what may be causing the illegal instruction error. The error occurs while reading in simulation files so maybe those files are not valid. There may also be a problem with the compiler, svFSI was built using GCC 9.4.

Cheers,
Dave
