## 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**

Tutorial in PDF format - Updated for SaloméMECA® 2010.2 Media:Piston_tutorial.pdf

## 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

**Link: Using the command **LIAISON_ELEM** **

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.

## Calculating assemblies with Code Aster®

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

**Link: Calculating assemblies with Code_Aster **

Includes:
