.load file

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

Creation of this file is controlled by the OLOAD I/O option.

Result	Description
Applied Load	Applied load vectors for linear static and inertia relief analyses.

The applied load file has the following format:

For each iteration, the following header is used:

iter Iteration NumIds

where:

iter	is a keyword denoting the beginning of a new iteration.
Iteration	is the iteration number.
Numids	is 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 LOAD:Spc_id(Datatype) subcase_label

where:

Id	is the output identification number for the subcase. This is not the same as the subcase ID used in the input data.
Number_of_nodes	is the number of nodes for which this output is requested.
Frequency	is 1.0 for static and inertia relief analyses.
LOAD	is a keyword declaring applied load information.
Spc_id	is the SID for SPC's referenced by this subcase.
Datatype	is a keyword indicating the type of subcase involved. (LOAD) declares data is for a linear static or inertia relief subcase.

The following information is then provided for each node, for which this output was requested:

NID X force Y force Z force X mom Y mom Z mom

where:

NID	is the node identification number.
X force	is the X force at the node.
Y force	is the Y force at the node.
Z force	is the Z force at the node.
X mom	is the X moment at the node.
Y mom	is the Y moment at the node.
Z mom	is the Z moment at the node.

The I/O option RESULTS controls the frequency of output for analytical results during an Optimization.
