sphereDrop example not working

cpadam · January 14, 2022, 16:18

When I try to run the sphereDrop example in OpenFOAM v2106 and v2112, I immediately get an error:

Code:

Maximum number of iterations exceeded: 100 when starting from T0:300 old T:5.593010375e+14 new T:5.593010375e+14 f:2.346267852e+18 p:82949.12625 tol:0.03

I get no other errors from blockMesh, setFields, etc. and meshCheck says the mesh is ok. It looks like the temperature exploded for some reason. I'd appreciate any help getting this to work, as this example is really close to the actual problem I want to run. If I can't get this working in the latest versions of OpenFOAM, does anyone know what older version(s) will run it successfully?

Can you give more details?

The compressibleInterDyMFoam sphereDrop tutorial runs fine for me on v2112 on WSL.

I'm running it on Ubuntu 21.10. I have made no changes to the case files. I tried to run it in both serial and parallel with the same results.

I'm sorry I cannot really help much here since I don't have Ubuntu 21.10 running in order to reproduce your problem.

Did you compile OpenFOAM yourself or did you install the precompiled packages with apt?
