Usage of .export file

abhishek_basak

Hi,

I am new to Code-Aster and am still coming to grips with it. I have a very basic and silly question. Where do I find the documentation (preferably English) for the .export file. I figured out that this file tells the Code-Aster solver as to what to do. Am I right??

Basically, the .export file keeps the structure of the differents files used by Aster to launch a calculation.

If you are launching Aster with Astk, you probably don't need to pay too much attention

Inside, you will find the different parameters used to launch the study:

*memory

*launch mode (etude, debug,...)

*the files used

-name of the mesh file

-name of the Eficas file (commands for the solver)

-the error file

-the message file

-the results file

and so on

So i guess you were right

Have a nice day

Hi,

Thanks for your reply. Unfortunately, I need to run on remote Linux terminal with no graphics support. Hence I cannot use the ASTK interface.

I was looking through form01a.export file and found the following lines,

P actions make_etude

...

A rep_mat ?ASTER_ROOT?/?ASTER_VERSION?/materiau

...

F mess ?ASTER_ROOT?/?ASTER_VERSION?/astest/forma01a.mess R 6

Any idea what is the general format for each line? My guess is that the first letter (for e.g. P) denotes what type of command it is (e.g. P may stand for a setting). Am I right?

Hi,

I've been looking for a documentation too, but until then I didn't managed to find one. My solution was to call ASTK to create a template .export file, and then rebuild this file with a script from template.

About lines format, I can guess :

* P stands for settings, followed by the variable and its value (space separated)

* F stands for File, and is aimed at connecting logical units (numbers) with input & output files.

* I don't know about A. Maybe A(rchive), e.g. folders for materials definition and so on...

Format: (I guess...)

> F mess ?ASTER_ROOT?/?ASTER_VERSION?/astest/forma01a.mess R 6

* F : File command

* mess : type = message (indicative, see below)

* ?ASTER_ROOT?/?ASTER_VERSION?/astest/forma01a.mess : the complete filename with path

* File type : R(esult) = Output // D(ata) = Input // C(ompress) = Compress data as gzip(?) files. Cumulative flags (e.g. input + output = 'RD', Output compressed file = 'DC', and so on...)

* 6 = Logical Unit #6 (= message output)

Since messages are always output by Aster on unit 6, I think the "mess" parameter isn't really usefull, but indicative... (as_run.py will execute a "mv fort.6 forma01a.mess" after computation if I remember right)

Some "standard" units are described in commands documentation (see "DEBUT()" for exemple). Otherwise ASTK has a built-in mapping table between unit number and file type. Too bad you can't use it to make a template .export file.

Hi Jérôme,

Thanks !!! That was really quite something. Sorry for my late response ... I was really busy. I will try to follow it up.

Hi,

Some general information about the export file options can be found in astk's utilisation document (u1.04.00 §2.1.4 and §8.1) and some syntax details are described in the developer document (d1.02.05).

As explained in u1.04.00 §8.1, the letters P, A and F stand for "paramètre", "argument" and "fichier".

The question has been asked a long time ago but recently I fell on this post before I found the two documents above. I hope I could save some time to some one else.
