optiSLang for ANSYS
3 ways to integrate ANSYS and optiSLang for parametric studies
• optiSLang inside ANSYS = Integration of optiSLang into ANSYS
Workbench
• optiSLang ANSYS Worbench node (ANSYS inside optiSLang) =
Integration of ANSYS Workbench Parameter into optiSLang
• ASCII file based interfacing including optiPlug for interfacing with
ANSYS Workbench

Benefit of ANSYS HPC Parametric Pack
Faster turn around time for multiple jobs
-
Geometry update and Result processing
will be performed sequentially on local
resource
-
Meshing, solution, result extraction
executed in parallel
Scaling factor depend on:
- time for geometry update
- time for meshing & solution
- hardware environment

Benefit of ANSYS HPC Parametric Pack
Get ready for RDO by multiplying base licenses
One base license set can be multiplied by
ANSYS HPC Parametric Packs
Now small, medium & large companies
can increase significantly the number
of parallel jobs!
