File Creation

This file is created when topography or shape optimization is performed. Output of this file is controlled by the I/O Option SHRES or by the GRID keyword on the OUTPUT card.

File Contents

Result Description
Nodal locations The nodal coordinates of the model for the last iteration of the optimization.

File Format

The file uses the following format for each grid in the model:
  GRID Id Cp X1 X2 X3 Cd Ps
Data
Description
GRID
Identifies this as a GRID card image.
Id
Unique grid point identification number.
Cp
Identification number of the coordinate system in which the location of the grid point is defined.
X1, X2, X3
Provides the location of the grid point in the global coordinate system.
Cd
Identification number of the coordinate system in which the displacements, degrees-of-freedom, constraints and solution vectors are defined at the grid point.
Ps
SPC associated with the grid.
