How to change units in ANSYS Fluent 2021 R2

Antimesher · March 8, 2022, 09:58

Hi,

I can't find a way to change the units in ANSYS Fluent 2021 R2 after importing the geometry from Solidworks --> design modeler --> Fluent meshing. It's currently set to metres and won't allow me to change it to mm (see attached image). Is there a reason for this and how can I rectify it?

Thank you

Probably because you are using workbench and the way the workflow works is that the CAD you export from solidworks and import into Fluent cannot be anything other than meters. Either CAD it in correct units in Solidworks, don't use workbench, or scale the mesh in Fluent after import.
