[Commercial meshers] Fluent Mesh into OpenFOAM

beratcagan · October 24, 2024, 08:31

Hey,

I am trying to import my Fluent mesh into openFOAM, but it gives me the following error:

--> FOAM FATAL ERROR: (openfoam-2406)
: file "Reactor_periodic_1M_ASCII.mesh.h5" not found

From int main(int, char**)
in file fluent3DMeshToFoam.L at line 845.

FOAM exiting

I created the Mesh in Fluent Meshing but it only allows the exporting of *.msh.h5 or *.msh.gz files.

In all the tutorials I watched on this topic, people where using ICEM oder Workbench Meshing, where they are able to export the mesh as *.msh.

I dont know if this might be the reason.

Is there a way to export the Mesh from Fluent Meshing as *.msh only?

gunzip the gz file and try with that

Go in Fluent Meshing to File > Preferences> General and set Default Format for I/O to Legacy. Then you should be able to export your mesh as *.msh.
