*SetFlexbodyInvariants()

Sets the nine boolean states for the flexbody invariants.

Syntax

SetFlexbodyInvariants(object_name, SOLVER_NAME, "TTTTFTTTT")

Arguments

object_name: The variable name of the set flexbody.; Data type: varname
SOLVER_NAME: The solver name (ADAMS only).
"TTTTFTTTT": The string of nine boolean's which set the state of each of nine invariants, respectively.

Comments

The nine boolean settings tell the solver which of the nine inertia shape integrals are to be used during the simulation.
