VPS - Getting started with Static and NVH simulation


Description

This course is an introduction to the implicit method and to the Virtual Performance Solution (VPS) solver. Participants learn to model in a simple manner static penetration tests, breaking and closing a vehicle door or the static load of vehicle parts (e.g. hood, backrest, beverage owner) and to carry out modal analyses of the Body in White (BIW). A global overview of the capabilities of the code, illustrated by industrial applications, is presented.

Audience

CAE engineers, designers and specialists in structural crash.

Objectives

Learn to perform basic linear and non linear static analysis and modal dynamic analysis using VPS Implicit.
