.gpf file

File Creation

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


Result	Description
Grid point force balance table	Grid point force balance table for linear static analysis.

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


	`ITERATION`			`Iteration_number`

Each iteration section contains a force balance table for each node, for which this output format was selected, in each linear static subcase.

These tables are given the following header:


	Grid point forces for node					`Node_id`				Subcase ID =		`Subcase_id`

Data: Description
Node_id: ID of the node to which the force balance table applies.
Subcase_id: User-defined subcase ID to which the force balance table applies.

The force information is provided, for each contributing element, constraint or load, in the following format:


	`Force_type`	`Element_id`			`x-force`			`y-force`	`z-force`		`x-moment`		`y-moment`	`z-moment`

Data: Description
Force_type: SPC - Force contribution of single-point constraints.; Appl. - Force contribution of Applied loads.; F-MPC - Force contribution of rigid elements and multi-point constraints. 2; Elem - Force contribution of elastic elements.; Rigid - Force contribution of rigid elements (RBEx, RROD, RSPLIN, and so on). 2; MPC - Force contribution of MPCs.; Total - The sum of all the force contributions.
Element_id: Only valid for force contributions from elastic elements or Rigid elements. This is the element's ID.
x-force: The x-translational component of the force.
y-force: The y-translational component of the force.
z-force: The z-translational component of the force.
x-moment: The x-rotational component of the force.
y-moment: The y-rotational component of the force.
z-moment: The z-rotational component of the force.

The I/O Option Previously Supported Results controls the frequency of output for analytical results during an optimization.
By default, the F-MPC output contains GPF contribution from both MPCs and rigid body elements (RBEx, RROD, RSPLIN, and so on). Additionally, rigid body element contributions and MPC contributions are separately printed to the .gpf file. The SYSSETTING(GPFMPC=FMPC/SEPAR) options can be used to control this output.
