BmMassProp

Platinum Platinum Platinum

Computes mass properties for the current model using densities assigned to its the components.

The density values used for the mass property calculations are defined by the Density property of the components and subcomponents, which can be either inherited from the main component of the assembly or a value.

The density of the main component is set in the Density field in the Mechanical Browser dialog (see the BmBrowser command).
