Creating Iso-static Restraints

You can create iso-static restraints on a body. Iso-static restraints are statically definite restraints allowing you to simply support a body. The program chooses automatically three points and restrains some of their degrees of freedom according to the 3-2-1 rule. The resulting boundary condition prevents the body from rigid-body translations and rotations without over-constraining it.

This option is generally combined with static scenarios and load self-balancing.

Before you begin: A structural analysis simulation containing a restraint set must be open.
