The Inertia Relief node serves multiple purposes. It provides a set of built-in constraints to avoid singularity, sets up the equation system to be solved for finding force balance, and allows the automatic generation of necessary nodes in the Model Builder tree.
Choose a method for selecting the Control points —
Automatic or
From selection input. When using the automatic selection, the control points are chosen by the program. In most cases, this works fine. There are, however, some cases in which certain points are not suitable as control points. Some examples are:
In such cases, you can use From selection input. Then, a
Point Selection section is shown. Select the points to be used for constraining the domain.
When the settings in this node are ready, click the Automated Model Setup icon (
) on the
Inertia Relief section toolbar and select the
Create Load Groups and Study (
) button to set up load groups for the load cases and a dedicated study.
