Recover the .msh from a .cas
I have a tricky problem to expose :
I would like to perform OF simulations starting from FLUENT data. However, I only have the .cas (also .dat) file. Indeed, the mesh was modified inside FLUENT (refinement, adaptation of cell size, etc), then the .msh file doesn't match with the simulation results.
Here, I have two possibilities :
* recover the .msh file from one of the ANSYS softwares
* convert directly the .cas file in OpenFOAM mesh.
I tried both of them without success for the moment.
As it is the relevant location of the thread, I will talk here about the first possibility.
Apparently it is possible to open directly a .cas file in icem or gambit, and then to save the mesh in a .msh file.
I tried with both softwares, but I get errors in all cases during the reading. I suppose it is due to the modifications on the mesh, performed inside FLUENT.
Here the ineternal error obtained in icem :
Not able to open file. Read error: wanted 1 bytes, errno 11
backend process has exited abnormally
Here the error obtained with gambit :
RAMPANT file to FIDAP7 file
File contains hanging node structure
Hanging nodes not supported
Does anyone have a suggestion for that ?
Thank you for your help.
Try to save your .cas file to ASCII format in Fluent and then convert to OF format.
I already tried this without succes.
see my post here :http://www.cfd-online.com/Forums/ope...foam-mesh.html
I would like to try also with workbench.
So, I created a mesh system and I imported the .cas file. Then, the imported mesh is checked. Is it possible now to export a mesh file from that ?
There is no File -> export in workbench ??
I don't manage neither to open the default meshing tool of workbench (maybe one can export the mesh from there?)
