*SetFlexbodyMexact()

Specifies which modal body coordinates the solver should not change during initial condition calculation.

Syntax

*SetFlexbodyMexact(body_name, SOLVER_NAME, m1, m2, ...mN)

Arguments

body_name: The variable name of the flexbody to which the set statement is referring.; Data type: varname
SOLVER_NAME: The solver name (ADAMS only).
m1, m2, ...mN: This represents the modal body coordinates that the solver will hold constrained as it solves for initial conditions that satisfy all constraints.; Data type: integer
