Hi everyone. Using 3DExperience Simulia, I've noticed strange options when defininig units system. 

In particular, when I set material properties, Simulia enforces me to put datas in a precise system units (for example densities are set in kg/m^3, Young modulus are set in MPa). This is ok!

But when I run an analysis, Simulia asks me for defining units...this is a bit confusing: if I already set material datas and masses using the metric sistem in kg and m, why should I set again units in the "Simulate" panel?

​​​​​​​Thanks!
