Hello,

I need to use MAC calculator on 2 modal models which are nearly identical. When I import with MAC calculator the 2nd rst, the model is not on the same scale than the 1st one. The 2 models have the same units (mm, t, N,  ...).

Did someone ever used successfully MAC calcultator ?

Thank you !

Hi,

Unfortunately, it doesn't help with the new NVH Toolkit. I know how to use MAC with APDL but I don't with NVH toolkit.

Hi VeraL,

I don't understand what you mean by "the model is not on the same scale", but yet you indicate they are of the same units. Can you please elaborate?
