.spcd file

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

File Creation

This file is created in a residual run when DMIG's are present in the model. The .spcd file contains displacement results at interface grid points and is used for stress recovery. A <filename>.<dmigname>.spcd file is created for each DMIG included in the model for the residual run.

File Contents

Result Description
Displacement Displacement results from a residual run.

Output is controlled by the I/O Option DISPLACEMENT.

File Format

The .spcd file has the following format:
For each iteration, the following header is used:
  SUBCASE SID  
Where,
Data
Description
SID
The identification number of the corresponding subcase.
Under each applicable subcase header, the following columns are:
  SPC SID GRID ID Component Displacement
Where,
Data
Description
ID
Is equal to 1000000 added to the identification number of the corresponding subcase.
GRID ID
The identification number of the interface grid at which the displacement results are output.
Component
The component in which the displacement results are output.
Displacement
The displacement result for a specific grid in the corresponding component.

Comments

  1. The ID column contains the identification number of the SPCD's which can be referenced by the loadstep definition during stress recovery. The identification number (ID) is derived by adding 1000000 to the subcase ID.
  2. The .spcd file can be included in the model containing the DMIG's (that is, the model which was used to generate the superelements) and SPC=ID can be added to the loadstep definition to reference the SPCD's for stress recovery.
