Overview<\/h2>\n

Code_Aster is a free and open source software package for civil and structural engineering finite element analysis, and numerical simulation in structural mechanics which was originally developed as an in-house application by the French company EDF<\/p>\n

Version 12.1.0-4 (testing) and 11.5.0-4 (stable) are installed on the CSF. They were compiled using gcc and Intel 12.0.5 compilers (EDF calibre). <\/p>\n

A more recent version of Code_Aster will be available on the system in late Oct\/early Nov.<\/p>\n

Restrictions on use<\/h2>\n

This software is open source and may be used by all CSF users. Please see the Code_Aster licenses webpage<\/a> for more details.<\/p>\n

Set up procedure<\/h2>\n

To access the software you must first load the modulefile:<\/p>\n

\r\nmodule load apps\/intel-gcc\/code_aster\/aster\r\n<\/pre>\n
Running the application<\/h2>\n
It is not possible to run Code_Aster simulations on the login node (the interactive job functionality has been disabled). <\/p>\n
Set up and submission of jobs is done through the ASTK GUI. The GUI uses your desktop\/laptop display so you need to connect to the CSF with X11 tunnelling enabled<\/a>. <\/p>\n
Serial batch Job maximum of 4GB of memory<\/h2>\n
    \n
  1. To start ATSK, after loading the modulefile type in the command: astk<\/code><\/li>\n
  2. A number of windows and messages will flash up briefly, and then you will be left with two. One entitled ASTK and one called ASJOB. In the ATSK window select the Study<\/em> tickbox, choose which version of Code_Aster you wish to run, and use the folder icon to select all the input and output files relevant to your job.\n
    \"astk-1-step1s\"<\/a>\n<\/li>\n
  3. If you get a warning like the one below do not worry about it, click ok to continue with the file selection.
    \n    \"astk-2-warnings\"<\/a>\n<\/li>\n
  4. Next, make sure the file types are correct. Then set the Total memory (MB)<\/em> to 4096<\/code> which is the maximum amount of memory a single core job can use on the main pool of CSF nodes. Also set Time (h:m:s)<\/em> to 168:00:00<\/code> which is 7 days and the maximum wallclock a job may have.
    \n    \"astk-3-filess\"<\/a>\n<\/li>\n
  5. When ALL of that has been set, click Run<\/em>. Make sure that, if asked, you save the current environment otherwise your job will not be submitted.<\/li>\n
  6. Once submitted you can keep track of your job using the ASJOB window. You can also see it from the CSF command line with the qstat<\/code> command. It is safe to close ASTK.<\/li>\n
  7. Once your job finishes the results will be available in a directory called flashuer<\/code> in files that resemble the name you saved it as and include a jobnumber, e.g. myasterjob.o123456<\/code><\/li>\n<\/ol>\n
    Serial batch Job maximum of 8GB of memory<\/h2>\n
    These jobs will use compute nodes with more memory than a standard compute node. Follow the same steps as for jobs up to 4GB, but at step 4 your need to do two things differently:<\/p>\n
