*SetForce() - single force with user subroutine

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.; Data 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.; Data type: string

Example

*ActionReactionForce( frc_bmp, "Rebound bumper", 
 TRANS_ROT, 
 b_bmp_contact, 
 b_bmp_attach, 
 p_contact, 
 mrk_ref)
 
*SetForce(frc_bmp, USER, `USER( { frc_bmp.id, %d }, 
 { frc_bmp.i.id, %d } , 
 { cr() }, `
 ` { frc_bmp.j.id, %d }, 
 { frc_bmp.rm.id, %d }, -10)`)

Context

*BeginMdl()

*DefineAnalysis()

*DefineSystem()

Comments

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