The #.grid file is an OptiStruct ASCII format results file.
This file is created when topography or shape optimization is performed. Output of this file is controlled by the I/O Option SHRES.

Description |
|
Nodal locations |
The nodal coordinates of the model at iteration # of the optimization. |
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. |
|||||
The # in the file name is the iteration number.
