_err.grid file

The _err.grid file is an OptiStruct ASCII format results file.

File Creation

This file is automatically created when freeshape and topography (or shape) optimization runs are terminated due to mesh distortion.

File Contents

Result	Description
Nodal locations	It contains the nodal coordinates of the distorted mesh for freeshape and topography (or shape) optimization.

File Format

The file uses the following format for each grid in the model:

GRID	Id	Cp	X1	X2	X3	Cd	Ps
where:
	GRID	identifies this as a GRID card image.
	Id	is the unique grid point identification number.
	Cp	is blank.
	X1, X2, X3	provide the location of the grid point in the global coordinate system.
	Cd	is the identification number of the coordinate system in which the displacements, degrees-of-freedom, constraints, and solution vectors are defined at the grid point.
	Ps	is the SPC associated with the grid.
