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.

Revision as of 16:55, 22 January 2009

Awright - this is done in a HURRY so take everything with a grain of salt - I hope to do some corrections later, or YOU can do it (edit) :)

Here I have uploaded some cases that are up to date with the latest Code_Aster 9.4 (C_A) along with *.astk, *.comm, mesh-files, *.hdf etc. etc. They should be usable 'as is'.

The point of these is, that I've struggled much with the out-dated examples (they are still valid, but wont run in later Code_Aster without much editing) and want to provide an easy way of copy/paste for newer users of C_A.

  • Thanks to everyone who helped me, and whos *.comm file I've taken stuff from - too many to write here :)

Software used:

  • Ubuntu 8.10
  • Salomé 4.1.4 for preparation of the geometry and meshing
  • Code_Aster 9.4 32bit, compiled with the Intel compiler for calculation

Computer used:

  • Dual core Intel 2.4GHz with 4G of RAM - all calculations are assigned 2 cores in ASTK - change this if you have more or less cores


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:
