[Commercial meshers] from Ansys: fluent3MeshToFoam Error

fanta · October 18, 2024, 05:12

Hi, i receive a Error from a Mesh I created with Ansys Workbench 2023 R2:

--> FOAM FATAL IO ERROR: (openfoam-2406)

Syntax error in expression at position:5
<<<<
0.24//1700
^^^^ near here

>>>>

My settings didn't change and the mesh ist not that big (~3GB). I never had that error. I use Ansys with Windows and dos2unix to convert to Linux.
Anyone knowing what to do?

Have you tried it without dos2unix? I use ICEM under Windows to create msh meshes and have always been able to convert them to the OpenFOAM format without using dos2unix first.

Regarding the error it doesn't make a difference, the error is still there.

Now this is still there, but i isolated the issue to the OpenFOAM environment:
-I meshed a simple pipe (14 mm pipe diameter, 500mm length) with an inlet, outlet and a wall with ansys CFD PrepPost, as usual.
Since i have two machines to run the OpenFOAM calculations, i tested with the other one and i have no problems with fluent3dMeshToFoam. Only on one machine, but there with every mesh. So i did a complete reinstall of OpenFOAM but that did not help, the issue still exists. I coinsider to reinstall Ubuntu.....
