Fatal Error using pimpleFoam

Lorg · February 24, 2020, 13:46

Hello everyone! I am pretty new to OpenFoam.

I am trying to simulate a rotating rim using pimpleFoam. I am mainly trying to use the propeller tutorial case on my problem. I get the following weird error message in the pimpleFoam log file for all 4 Procs:

Code:

1] --> FOAM FATAL ERROR: 
[1] 
    [pcorr[1 -3 -1 0 0 0 0] ] == [div(phi)[0 0 -1 0 0 0 0] ]
[1] 
[1]     From function void Foam::checkMethod(const Foam::fvMatrix<Type>&, const Foam::DimensionedField<Type, Foam::volMesh>&, const char*) [with Type = double]
[1]     in file /opt/OpenFoam-src/OpenFOAM-dev/src/finiteVolume/lnInclude/fvMatrix.C at line 1277.
[1] 
FOAM parallel run aborting

Does anyone know what the reason could be?

Thanks!

Check if you have provided dimensions of input fields correctly.

Thanks!

I thought my dimensions were correct but apparently you have to use [0 2 -2 0 0 0 0] for pressure when using pimpleFoam instead of [1 -1 -2 0 0 0 0] which is the normal unit for pressure. That confused me.

Hi Lorg,

All incompressible solvers in OpenFOAM uses pressure normalised by density. This is why your pressure file has the dimension [0 2 -2 0 0 0 0].

Ah cool, that makes sense. Thanks Yann!
