Simcenter 3D

How can I find out the mass of the total Motion model? How can I find the center of gravity, CG, of the entire system?

Starting with Simcenter 3D 2021.2, it is possible to plot the mass of the whole system in a Motion simulation.

This value can be found by selecting the solution in Motion Navigator, expanding the XY Result View, then plotting the system:mass element.

In a similar fashion, the coordinates of the center of gravity can be plotted using the following System variables:

Note that for dynamics analyses, since the mechanism (system) is in motion, the X, Y, Z coordinates will change.

The value of these variables at t=0 represent the initial position of the CG.
