Hello.
I want to do simulation of a wedge pipe. I have created geometry in Salome and mesh by ideasUnvToFoam. But when I check the mesh, the error shows like this:

Cannot find file "points" in directory "polyMesh" in times 0 down to constant


I use simpleFoam/pizyDaily as solver.

How can I fix this? Thanks in advance.

Hello Yihong!

Most properly you are using second order elements. If you do, then try it without seond order elements.

As plan B that works for me you can try the following:

- Download the script:

salomeToOpenFOAM.py

from here:

https://github.com/nicolasedh/salomeToOpenFOAM

and save it to your working folder

- Generate the mesh you want to convert and save the *.hdf file (SALOME)

- In SALOME mark the mesh you want to export

- File -> load script -> salomeToOpenFOAM.py

- Wait until the mesh exported. Finished exporting is printed in SALOME console

- A new folder will be generated in your case called mesh(_1) and includes the mesh

- Copy the mesh folder (polyMesh) to constant

Regards

Hi Peter. Thanks for your reply.

I just copy the tutorial containing no polyMesh folder in constant folder. No idea about that seond order elements.

Hello!

Well, as I understood, you generated the mesh using salome...

Am I right?

If yes, then you need do deactivate the second order elements, cause the ideasUnvToFoam have a problem converting the mesh to my poor knowledge.

Send please the case. Show please the log file of the ideasUnvToFoam.

Could you be more specific about what can I do? And yes, I do use salome.

The log file is as follow:
