Calculate object inertia

Alberto Damas · October 1, 2015, 05:28

Hello, I want to use the DFBI tool so I need the inertia values of the body.
¿Is there any way to calculate this with the material density?

Thx.

do you have a CAD file of this object or are something you created using star's native CAD tools?

I created it with the star ccm tool. I thought of creating a solid region but I don't know how to use the interfaces.

Now I have two regions, the turbine geometry subtract to a cylinder (this has overset mesh) inside another bigger cylinder. So I haven't set any turbine material properties, just the mass demand by the DFBI tool.
