Hi everyone,
I'm currently working on a calculation with OpenFoam and have a problem with simpleFoam.

First of all I have to say that I'm only 19 years and started working with OF half a year ago. In the beginning I got some help, but most of it I have learned on my own (mainly because it really makes fun ). So I'm not extreme high experienced.^^ But during the time, the work with OF works quite well.

At the time I'm trying to simulate a litte car.
"BlockMesh" & "snappyHexMesh -overwrite" worked both without any problems and according to checkMesh the mesh is ok. In addition at the begining I reduce the scale of the imported .stl with
Code:
surfaceTransformPoints AutoWF2014.stl AutoWF2014-m.stl scale '(0.001 0.001 0.001)'
because the CAD program exports in mm.
After doing these steps it looks like this:
https://www.dropbox.com/s/bt3n4x6njz...Bild1.jpg?dl=0
https://www.dropbox.com/s/k65hvf9opy...Bild2.jpg?dl=0

But when I start "simpleFoam", I recive an error right away:
https://www.dropbox.com/s/wonrsug9u6...Bild3.jpg?dl=0
https://www.dropbox.com/s/9g8fgj5i7t...Bild4.jpg?dl=0
https://www.dropbox.com/s/mscaxrcaua...Bild5.jpg?dl=0

Any ideas what I can change? Thank you in advance!
Best regards, Michael

Hi,

First of all: If you want to post code, click on the "Go Advanced" button and for code click on the "#"-wrap code button. Put your code / log files between the "CODE" tags. No pictures from suspicious places...

Anyway
It looks like the pressure solver doesn't work. Can you post the fvSolution and fvSchemes files (as I wrote above).

Hi RodriguezFatz,
thanks for your reply.
The fvSolution file looks like this.

Hi,

Also please post your:

1. checkMesh output
2. Initial and boundary conditions (archive of 0 folder)

As the error happens during solution of pressure equation, you can start by changing GAMG solver to PCG (or play with GAMG settings).

Hi,
Ok, can you try:
Code:
p
{
        solver           GAMG;
        tolerance        1e-12;
        relTol           0.1;

        maxIter         20;    

        smoother         DIC;
    
        nPreSweeps       1;
        nPostSweeps      1;
        nFinestSweeps    2;

        cacheAgglomeration true;

        nCellsInCoarsestLevel 1000;
        agglomerator     faceAreaPair;
        mergeLevels      1;
     }
Why do you use an old version of openFOAM? Edit: Ok, it's just the file...

Gleitkomma-Ausnahme (Speicherabzug geschrieben)
I use OpenFoam 2.3.0. I know that 2.3.1 was published in December, but had no time to install the new version. Are there so many advantages that I should do it immediately?

Hi,

as GAMG fails try PCG, i.e.

Code:
    p
    {
        solver          PCG;
        preconditioner  DIC;
        tolerance       1e-8;
        relTol          1e-2;
    }
Also you've got 55 degree of maximum non-orthogonality, increase number of nNonOrthogonalCorrectors, start with 1-2.

Hi alexeym,
thanks for your idea with PCG, but the error occures at the same time.
Also to increase the numbers of nNonOrthogonalCorrectors doesn't helps.

Another idea: Could the error come from the possibility that the stl file has somewhere a little hole and is not completely closed?

Flexi, checkMesh says that mesh openness is not a problem...
But what does that mean:
Code:
The mesh has multiple regions which are not connected by any face.
  <<Writing region information to "0/cellToRegion"
  <<Writing region 0 with 270433 cells to cellSet region0
  <<Writing region 1 with 1 cells to cellSet region1
  <<Writing region 2 with 1 cells to cellSet region2
  <<Writing region 3 with 1 cells to cellSet region3
  <<Writing region 4 with 1 cells to cellSet region4
  <<Writing region 5 with 1 cells to cellSet region5
  <<Writing region 6 with 1 cells to cellSet region6
  <<Writing region 7 with 1 cells to cellSet region7
  <<Writing region 8 with 1 cells to cellSet region8
Can you post a picture of your domain?

Dear Flexi1095,

the error is in your mesh. You have there a 8 regions with 1 cell. Please try to create another mesh.

Hi RodriguezFatz & betakv,

@RodriguezFatz: see attachment
So if I understand correctly, the problem comes with snappyHexMesh, which creates the 8 regions with only 1 cell. I have repeated the same process, but there are again these 9 regions.
Do you have an ideas what could cause this problem?

Thanks for your help so far!

Hi Rodriguez,

Have you managed to find a solution for this problem?

Sorry to bring this post back. I am now facing the exact same problem with you. I have posted the problem in the forum for 2 weeks but with no single response. It seems the problem has been here for more than at least 2 years but no one has seems to know why.

Could anyone help me with this problem please?

Jason
