Hi all, my question is, If i made my CAD modell in mmKs sstem ( in Creo), and than import the step file into the CFD program, the unit system will be still mmKs and because of this the pressure unit will be KPa?

If you are expecting force in Newtons then it with be N/mm^2, which equals to megapascal (MPa).

You can try changing the target units while importing the geometry or check if u can interpret the dimensions from mm to m scale in Creo.

I would recommend using SimLab for CFD setup. It supports units.

You can also scale the geometry once you import to HyperWorks CFD (if indicating the desired scale during import doesn't work).  Geometry Ribbon > pull-down next to the 'Edit' group title > Scale

Hello Barnabas,

When talking about CAD geometry then the units refer to distance units (Meters, Inches, etc.). In SimLab after the import of your model you are able to set different options regarding units (Bottom right of your screen).

To check if the imported model has the correct dimensions you should use the Measure tool and if something is not correctly synchronized, then the transform tool can scale it to your demands.

Measure and Transform tool respectively:

Take care,
