Hi everybody,

I am currently trying to run a simulation with rhoSimpleFoam.
I used the tutorial case "angledDuctExplicitFixedCoeff",
replaced the files in the polyMesh-folder with my own mesh and adjusted the boundary conditions.
When I tried to run rhoSimpleFoam on the case, I got the following error message:

#0 Foam::error:: printStack(Foam::Ostream&) at ??:?
#1 Foam::sigFpe::sigHandler(int) at ??:?
#2 in "/lib/x86_64-linux-gnu/libc.so.6"

Floating point exception (core dumped)

I have already searched the forums and I know, that to display the lines I would need to use the debug-version of OpenFOAM.
However, since I am on a university computer, I would rather not change anything in the program files of OpenFOAM.
I am using OpenFOAM 2.3.1 by the way.

From the error message I gather, that it is a problem with the thermophysical properties.
I did not modify them in any way, they are still the same as in the tutorial case.
I am not sure how to change them since I can't figure out, where they are used.

If you need to have a look at any of my files let me know and I will post them as soon as possible,
but so far I don't really know what you are going to need.

By the way I don't think it is a problem with k or epsilon being zero.

I hope you can help me.

Sincerely,
Sabrina

Actually I think it may be a problem with my mesh.
I executed a checkMesh -allTopology -allGeometry and it failed 2 checks.
So I assume, the error was caused by this and I will need to
modify my mesh in order to run rhoSimpleFoam properly.

Hi Sabrina,
I'm stuck to a similar problem, but my mesh is all ok.

Could you provide some useful instructions, you found about the debug, to understand which line of the code gets the error?
I would be really grateful if you or someone else want/s to share these instructions here or in my post

Thanks

Thumbs up debug mode, etc.

I think most of the advice to help with this error I found in this thread:
Foam::error::PrintStack

It took me a while to find it again, but here are the instructions on the openfoamwiki.

THe problem appears due to the boundary conditions. It may be due to the Pressure outlet, the units are established in Pa and you should take into account a total pressure, not a p/rho (m2/s2) pressure as it is taken in incompressible flow (simpleFoam).
