# Contrib:Claws/Code Aster/9.04cases

**<-Link: Back to Contrib:Claws/Code_Aster**

*Software used:*

**Ubuntu 8.10****Salomé 4.1.4**for preparation of the geometry and meshing**Code_Aster 9.04**32bit, compiled with the Intel compiler for calculation

*Computer used:*

- Dual core Intel 2.4GHz with 4G of RAM

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

Note: These cases are for loading into **ASTK** and not for running from e.g. **SaloméMECA** - **Salomé** should only be used for viewing the geometry, mesh and postprocessing the result files.

I hope these cases prove valuable for learning a bit more about **C_A**

These are my current uploads:

- MathCAD_-_Beam.xmcd.pdf This is the basis for the calculations. It is used to compare the results obtained from
**C_A** - Study_Beam-linaer.tar.gz H-Beam imposed with a ridiculous load, linear static/elastic. Linear mesh
- Study_Beam-quad.tar.gz This is the same calculation, but with a quadratic mesh
- Study_Beam-lin-ensight.tar.gz This is the same calculation, with a quadratic mesh but with Ensight® output format
- Study_Beam-nonlinear.tar.gz This is a nonlinear/plasticity calculation of the above study - It relies heavily on the tutorial of PCarrico on plasticity, so refer to this one if my comments are inadequate.

- This is a study on a tensile strength test I did on first semester - I can't remember the forces required, but that it snapped at about 10mm. This is a nonlinear calculation using the same Alu. material used in the above calculation.

This is an example of contact - the aluminum rod is pressing down on a solid steel block. The example introduces an new concept (for me): creating a *linear* mesh in Salomé, loading and converting this mesh in **C_A** to a *quadratic* mesh, run the calculation and the project the results back to the linear mesh. This saves space on the mesh/result file but retains the finer results from the quadratic mesh. The *.comm file is documented to some degree, but some concepts I don't fully understand yet.
