Hi,

I'm running a 6dof simulation and after t = 0.3, the simulation stops. The error given is:

I've read this debugging tutorial:

but I still don't understand where the error comes from.

Should I change a different pressure solver? Or I must change my fvScheme?

Hope someone can help.

Thanks!

Hi quarkz,
The information you posted here is not enough to determine where the problem came from. But from the information you provided, it seems like a computation crush. You can try to check calculation parameters, mesh.....

Best wishes

Implement the things found in the link and compile your customised solver in debug mode. Then you can locate your errors with line numbers where you can easily reach your mistakes.
Thank you
