How do I proceed?

Hey All,

I was using a surface mesh and that could be the cause of the error. Now, trying hard to volume mesh but memory allocation error can't seem to be resolved. Physical RAM - 4GB, virtual- 10GB in Windows and 26Gb swap in ubuntu don't seem to be sufficient. Any suggestions?

Best Regards,
Pranav

Hey!

This is my final year engineering project and I'm dealing with a fabric which is 0.5mm. I did use Netgen 1D-2D-3D in Salome. The algorithm does a neat job optimizing lenghts of elements along the edges. My model is a flexible wing with a missing nose to facilitate RAM air inflation just like parachutes hence meshing is bound to get tricky.

I simplified the problem, decided to permute with gemoetric parametersin 2D analysis. Unfortunately the geometry couldn't be reparied in Salome (despite editing tolerences to 1e-20). Now going for a infinite-wing wind tunnel setting. The flow field is 50mx50mx0.02m (z-x-y in standard convention). Now I get another error while running the code in OpenFOAM.

What could be wrong?

PS:
"..." means I haven't pasted those lines here.

Hello,

In the case of Code_Saturne, could you post the listing an error* files, as mentioned in the error message you posted ? Could you also post the preprocessor.log file ?

Yvan

Greetings Yvan,

The error file mentioned a boundary condition error. The root of the error was that I created a geometric group -Inlet- with two faces and subsequently used this group to create a mesh group from geometry. The two aforementioned faces formed the inlet face of my rectangular flow field. The error was corrected by making each surface an inlet and greating mesh groups from gemoetry unique to each face.

However, now I hit another error,.

I'm having trouble uploading the .tar file. When I hit open, the dialog box disappears and I don't see it listed in the attachements.
What must I do to upload?
