Version date: 2nd January
2013
Codes:
PAM-CRASH -
A general purpose Explicit and Implicit finite element code for impact, crash
and static simulation
PAM-FORM -
An Explicit finite element code for composites drape simulation
PAM-OPT -
A general purpose optimisation code
Visual Mesh -
For handling CAD data and finite element mesh generation
Visual Environment -
For definition of model entities (loading, boundary conditions, etc.) and
material properties
Visual Viewer -
For visualisation of results
ESI education versions of the Explicit finite element code PAM-CRASHTM and the
pre-and post-processors (Visual) to generate models and visualise results are
available at http://virtualperformance.esi-group.com/education. Currently these codes are
available free after registration.
These downloads provide older
versions of the codes (2008) than used for the tutorials, but they will work.
However, within the next few months the current version of the codes (V2012)
will be available which are fully compatible with the tutorials.

·
For tutorials 1, 3,
5 and 13 Visual Mesh is used to
generate the FE mesh. For the remaining problems completed FE meshes are
supplied to limit the length of the exercises. For each tutorial completed PAM-CRASH/PAM-FORM analysis datasets
are also provided.
·
Tutorials 1-2, 3-4 and
5-6 should be tackled together as, in each case, the first part mainly concerns
building to model which is then followed by the second part for analysis.
·
Each tutorial has
requires about 1-2 hours to complete. The links below access documentation,
meshes and completed datasets for each tutorial.
