Learning Outcome and Course Requirements — Lesson 1

This lesson gives a brief overview of the course, the learning outcome, and course requirements. It also provides a short description of the simulation model used. If you would like to learn more about parametric analysis in general and discover its uses, you can take the course Parametric Analysis and Optimization.

Technical Requirements

• LS-DYNA Distributed Memory Parallel installed
• Set system or user environment variable ANSYS_SYSDIR=winx64 and restart optiSLang afterwards
• For optiSLang <version> v231, v232, and v232 SP1 missing DLL for LS-EXTRACTOR: "libifcoremd.dll" and "libmmd.dll"
  • either add to the system/user environment variable PATH: \optiSLang\lib ,
  • or copy both DLL from this directory to <oSL_install_dir>\plugins\lsx\bin 
  • <oSL_install_dir> usually is: 
    • either "C:\Program Files\ANSYS Inc\<version>"
    • or "C:\Program Files\Dynardo\ANSYS optiSLang\<version>"
• CPU time per design: Approximately 6200 CPU seconds
• Elapsed time per design using 4 cores: Approximately 25 minutes
• Total running time for the whole study (70 designs) for serial execution: 1.5 days
• Free disk space: Approximately 7.5 GB, approximately 5 GB (LSTC_D3DUMP=off)
• Minimum number of licenses required: 1 x optiSLang_level2, 1 x dyna, 3 x dysmp
