ASTK - Aster

[under construction - nearly empty box]

For the calculations we need two input files:

• mesh file, this has been discussed in the previous part
• command file, a list of commands for processing by Aster

Several output files and a directory are generated by Aster, the most common are:

• error file, *.err
• message file, *.mess
• results mesh file, with displacements, stresses, strains of the elements and nodes
• base folder, for storage intermediate results

The interface between the input files, output files and Aster is called ASTK. There all the input and output files are defined. The types are defined, eg. mesh file. Whether the files will be read or written to. And the Fortran logical file number or unit number LU is defined.

The input row for the file names is used for the link between the filenames and the logical unit numbers (UNITE in the command file). So in this case the first file is ./shell.comm, type comm -first row- and logical unit LU is 20. This file is an input file hence the R is ticked.

This is also the default
