OptiStruct Panel

Use the OptiStruct panel to execute an OptiStruct run on your desktop.

Location: Analysis page
Note: Available in the OptiStruct solver interface.

The OptiStruct panel eliminates the need to export the input file, to use the Solver panel to execute the job, and to select the results file for post-processing. There is also a HyperView button in the panel that will launch a session of HyperView with the results of your OptiStruct run.

The exported file can contain all or only the displayed model information.

The screen output is automatically set to SCREEN, OUT. This displays the OptiStruct output to the DOS and UNIX window, respectively.

Panel Option

Option Action
input file: Navigate to the desired input file.
export options Select a method for exporting data to the input file before executing an OptiStruct run.
Export everything to the input file.
Export only what is displayed to the input file.
Export what is selected in the Entity State Browser.
run options Select a run option before executing an OptiStruct run.
Solve the model as is.
Start an optimization regardless of whether ANALYSIS or CHECK is specified in the control cards section.
Start an analysis regardless of what is specified in the model.
Start a check run regardless of what is specified in the model.
Restart an optimization run. The input file (<filename>.fem) and a restart file (<filename>.sh) must be specified. No model is exported.
Run a reanalysis on a topology optimization. The last iteration will be reanalyzed without penalization.
If the density threshold given is less than the value of MINDENS (default = 0.01) used in the optimization, all elements will be assigned the densities they had during the final iteration of the optimization. As there is no penalization, stiffness will now be proportional to density.
If the density threshold given is greater than the value of MINDENS, those elements whose density is less than the given value will have density equal to MINDENS, all others will have a density of 1.0.
The input file (<filename>.fem) and a restart file (<filename>.sh) must be specified. No model is exported.
memory options Specify the memory limit, and decide whether or not to run an in-core or out-of-core solution depends.

The memory default can be changed using the system setting (SYSSETTING) option OS_RAM. You can assign a different memory limit for an individual run by entering a value for memory in upper limit in Mb= or by defining the -len option in the run script.

include connectors Include predefined connectors in the output file.
options: Specify any additional options to write to the solver.

Command Buttons

Button Action
Save as Choose the run location and provide the filename for the OptiStruct input file.
OptiStruct Automatically perform the following procedures:
  • Export an OptiStruct input file (using the location and filename as defined in the input file: field) for the Engineering Solutions model according to the selected export option (all, displayed, or custom).
  • Execute the solver with the specified run option (none, optimization, analysis, check, restart or reanalysis) and memory option (default or user defined upper bound).
  • Load the resulting .res file for post-processing in Engineering Solutions.
HyperView Launch a new session of HyperView and load the resulting .mvw file from the OptiStruct run. (Specifically this loads the .mvw file corresponding to the filename in the input file: field).
view .out View the .out file after a run has been submitted.
