Now set up the process chain. In the simplest case, a single Stage is required to interface with a solver, e.g. LS-DYNA. In more complex cases further stages can be added, e.g. for a pre-processor or post-processor.
Home Screen Process Flowchart
Select the already available Stage box in the process flow (here crash).
A window Stage stagename shall open.
Define Input File Name and Command
For Command specify the solver executable.
For Input File browse the parameterized file.
Choice on handling number of concurrent jobs can be made suitably in this section.
Design Parameters.
The design parameters in the input files specified in the Setup can be viewed.
For LS-DYNA, the input files are usually parameterized using *PARAMETER
Otherwise the LS-OPT parameter format <<parameter_name>> may be used.
Now define the results to be extracted from the solver output database (to be used as objectives or constraints in the optimization phase) using the interfaces available in the Histories (curve data) or Responses (scalar values) tab, respectively.
Responses
Select a response type from the several options available in Add new column located on the right side. A response can be a result of a mathematical operation applied to a time history curve or a previously defined response, or can be directly extracted using the standard LS-DYNA interfaces or a user-defined interface.
Upon selection a seperate window appears where the user can define the reponse properties.
The responses defined can be reviewed later for alterations if necessary.
