.spcf file

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

File Creation

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

File Contents

Result Description
Single-point force of constraint Single-point force of constraints for linear static analysis.

File Format

The SPC reaction force file has the following format:
For each iteration, the following header is used:
  iter Iteration Numlds
Data
Description
iter
Keyword denoting the beginning of a new iteration.
Iteration
The iteration number.
Numlds
The number of subcases for which this output is created.
Each iteration section is divided up by subcase. Output for each subcase starts with a line in the following format:
  Id Number_of_nodes Frequency SPCF:Spc_id(Datatype) subcase_label
Data
Description
Id
The output identification number for the subcase. This is not the same as the subcase ID used in the input data
Number_of_nodes
The number of nodes for which this output is requested.
Frequency
Is 1.0 for static analysis.
SPCF
Keyword declaring SPC-force information
Spc_id
The SID for SPC's referenced by this subcase.
Datatype
Keyword indicating the type of subcase involved.
(LOAD) declares data is for a linear static subcase.
SPC-force information is then provided, for each node, in the following format:
  Node_id x-force y-force z-force x-moment y-moment z-moment
Data
Description
Node_id
The node identification number.
x-force
The x-translational component of the force at the node.
y-force
The y-translational component of the force at the node.
z-force
The z-translational component of the force at the node.
x-moment
The x-rotational component of the force at the node.
y-moment
The y-rotational component of the force at the node.
z-moment
The z-rotational component of the force at the node.
