Re: Import ANSYS CFX Mesh to Fluent
I convert the CFX mesh in ICEM CFD to fluent mesh but I have a problem to import mesh files into Gambit. I got this message error
"Gambit is unable to import |utility fe2ram -m12-006 -d3 -tRAMPANT -oFIDAP7 C:\~\fluent.msh Further information may be available in the Gambit start" Any advice? Many thanks Noureddine |
Re: Import ANSYS CFX Mesh to Fluent
You can specify periodic boundary conditions in FLUENT via the TUI.
Hope that helps. |
Re: Import ANSYS CFX Mesh to Fluent
I do CFX-to-Fluent imports all the time and this is fairly common. Basically when Fluent imports a mesh from CFX it converts it to a RAMPANT format, which can cause your periodicity to become undefined. There is a command available via the TUI called "repair periodic" that is meant for these situations. Another thing to check when you bring your CFX mesh into Fluent is that the rotation axis of your fluid domain is oriented properly (default is z-axis). Usually I just simply remake the periodics via the TUI as I normally would, which works mostly fine for me.

Thank you guys,
I did grid/modify-zones/make-periodic and select the two periodic surfaces and it works. Noureddine |
