# Contrib:Claws/Code Aster/10 x cases

(diff) ← Older revision | Latest revision (diff) | Newer revision → (diff)

## Software used:

(Updated along with the latest tutorial - some tutorials might need tweaks to work with later versions)

• Ubuntu 10.04 64bit
• Salomé® 5.1.5 for preparing the geometry, meshing and post-processing.
• Code Aster® 10.3 64bit, compiled with the Intel compiler for calculation

Computer used:

• Dual core Intel 2.9GHz with 4Gb of RAM

I have tried to comment the *.comm files as well as I could, but I am far from an expert on Code Aster® so use these files only as an example of the file structure/the Code Aster® way of thinking.

## Piston tutorial

I have updated the original piston tutorial also found on this wiki, to comply with SaloméMECA 2010.2 - A great introduction for absolute beginners to SaloméMECA and Code_Aster

## Applying Torque and using parameters

This case deals with applying torque to an object in a linear calculation and using parameters to control the calculation.

Includes:

• Applying torque - LIAISON_SOLIDE
• Using parameters
• Linear static calculation, incremented
• Creating an animated GIF file of the result

## Using the command LIAISON_ELEM

Apply the command LIAISON_ELEM using beams to substitute 3D geometry to reduce the work load of a calculation and simplify geometry

Includes:

• LIAISON_ELEM:Connecting 3D structures to 1D elements; using beams to substitute 3D geometry
• Describing geometry with AFFE_CARA_ELEM
• LIAISON_UNIF

## Simulating a two segment pendulum with DYNA_NON_LINE

A short introduction to using DYNA_NON_LINE to simulate a two segment pendulum.

Includes:

• Cables
• DYNA_NON_LINE
• Tracing curves with Code_Aster and XMGrace

## Calculating assemblies with Code Aster®

A guide to assembling separate mesh files, calculating stresses and strains, then disassembling for individual post processing.

Includes:

• ASSE_MAIL for assembling the meshes
• LIAISON_MAIL for connecting the meshes
• IMPR_RESU - RESTRAINT for only printing the relevant results to the meshes
• Note on interpreting Von Mises stress in Salomé®/Code Aster®

## Plasticity tutorial

Plasticity tutorial - for CAELinux.com by Paul Carrico, translated and reworked by Claus Andersen

Includes:

• Plasticity Nonlinear deformation of an aluminium wheel rim
