.mpcf file

The .mpcf file is an OptiStruct ASCII format results file.

File Creation

Creation of this file is controlled by the MPCFORCES I/O Option.

File Contents

Result	Description
Multi-point force of constraint	Multi-point force of constraints for linear static analysis.

File Format

The file is divided up by iteration. Output from each iteration starts with a line in the following format:

	ITERATION				Iteration_number
where:
	ITERATION				is a keyword denoting the beginning of a new iteration.
	Iteration_number				is the iteration number.

Each iteration section contains the multi-point force of constraint for each node, for which this output format was selected, in each linear static subcase. Each subcase section is given the following header:
	MPC forces for Subcase						Subcase_id
where:
	Subcase_id			is the user-defined subcase ID to which the mpc forces apply.

MPC force information is then provided, for each node, in the following format:
	Node_id	x-force				y-force		z-force	x-moment	y-moment	z-moment
where:
	Node_id		is the node identification number.
	x-force		is the x-translational component of the force at the node.
	y-force		is the y-translational component of the force at the node.
	z-force		is the z-translational component of the force at the node.
	x-moment		is the x-rotational component of the force at the node.
	y-moment		is the y-rotational component of the force at the node.
	z-moment		is the z-rotational component of the force at the node.
