Introduction to
Ansys LS-PrePost

Course Overview

LS-PrePost is an advanced pre and post-processor that is delivered free with LS-DYNA. The user interface is designed to be both efficient and intuitive. LS-PrePost runs on Windows, Linux, and Unix utilizing OpenGL graphics to achieve fast rendering and XY plotting. 

This class will teach you how to pre­pare key­word in­put files for LS-DY­NA and to post-process the re­sults us­ing LS-Pre­Post.

Prerequisites

  • Fa­mil­iar­i­ty with gen­er­al fi­nite el­e­ment ter­mi­nol­o­gy is help­ful
  • An in­tro­duc­to­ry class in LS-DY­NA is rec­om­mend­ed but not nec­es­sary
  • A technical education and background is recommended but an engineering degree is not required

Teaching Method

The class is divided 50/50 between lecture and hands‐on workshops.
