*SetForce() - single force with user subroutine for command sets

Sets the values for a translational, rotational line of action and single component rotational force when a user-defined subroutine is used to model the force expression.

Syntax

*SetForce(force_name, USER, `expr`)

Arguments

force_name: The variable name of an existing force.; Type: Varname
USER: This argument indicates the user-written subroutine is used to model the force value.
expr: The solver expression that sets the arguments for the user-defined force.; Type: string

Comments

The solver force entity type is dependent on the force type referred to by the *SetForce() statement.
