VPS Explicit - Basic Crash Modeling
Basic knowledge of the Finite Element Method is beneficial.
For efficient and successful working with VPS/PAM-CRASH, a solid understanding of the basic algorithms of an explicit code, as well as of the essential program options, are necessary. Therefore, after a short overview of the history of crash simulation and the general capabilities of VPS/PAM-CRASH, the course will give an introduction to how to solve structural problems with explicit time integration. Subsequently, all options will be explained, which are required to perform a standard crash simulation. The course is accompanied by exercises.
