Mass Properties
Introduction
You can add one or more Mass Properties nodes to create variables for and compute the following quantities for a model component:
mass1.CMX, mass1.CMY, mass1.CMZ
mass1.IXX, mass1.IXY, mass1.IXZ, and so on
mass1.Ip1X, mass1.Ip2X, mass1.Ip3X, and so on
mass1.Ip1, mass1.Ip2, and mass1.Ip3
The namespace of the variables — mass1 in the table above — is unique for each Mass Properties node.
In general, the characters X, Y, and Z in the variable names in the table above are replaced by the coordinate names in the selected frame.
If your license includes the Structural Mechanics Module, see the Structural Mechanics Module User’s Guide for information about additional functionality for computing mass properties taking things like beams, point masses, and swelling into account.
Use a Global Evaluation node, for example, to evaluate the resulting measurement quantities, which you can select from a Definitions > Mass Properties submenu after clicking the Replace Expression () or the Insert Expression () button.
