Zrun#

Description#

This command runs the main Z-set program, which contains the installed modules if available (e.g. FEA, Mesher, Simulation and Optimization). Running with the -h switch will display all the installed problem types which are available in the current executable. Running with -H will show a much larger display of available commands.

Syntax#

% Zrun [options]problem   \(\hookleftarrow\)

  1. Basic control options

    CODE

    DESCRIPTION

    -test_license <M>

    Check the license for the module <M> (by default the license fem is checked)

    -smp <cpu>

    Activate multithreading where available (OK for calcul and local post-processings)

    -mpi <np>

    Launch in parallel with a master process (limited to localhost, OK for calcul, post and glue). If calculations are being performed on a computing cluster, please reach out to system administrator).

    -mpimpi <np>

    Launch in parallel without master process (limited to localhost, not ok for glue)

    -N <num>

    run Nth instance of the problem (When multiple problems of the same type are defined within a single input file).

    -limit <t>

    Limit job CPU time to t seconds (only for some platforms).

    -zbb

    Use the ZeBaBa library.

    -preload

    preload material input file (see Zpreload)

    -Ni

    read with native format (system format).

    -Nino

    do not read with native format.

    -No

    write using native format.

    -Nono

    do not write using native format.

    -Q

    silent screen output.

    -v

    verbose mode (prints machine architecture, Global parameters and their values, material model variables, …).

    -param_list

    list all global parameters.

    -H

    outputs the keywords for all installed modules.

    -h

    print help

    Note

    The Z-set default format is big-endian. However, many modern processors use the little-endian format. The -Ni or -No switches can be used to specify the appropriate endianness to either read from Z-set data files or write to them using native system write/read functions.

  2. For debugging purposes, the following options are available

    -db

    run in debugger (gdb only)

    -g

    run debug version

    -vg

    Run the debug version under ValGrind supervision

    -vk

    Run the debug version under ValKyrie supervision

    -itc

    Run the debug version under Intel Thread Checker supervision

    -imc

    Run the debug version under Intel Memory Checker supervision

  3. Installed modules (usually specified in the input file with ****-level commands). To see all currently available modules use the -H switch.

    -m

    run batch mesher (****mesher).

    -fem

    run a FE problem (****calcul).

    -o

    run optimizer (****optimize).

    -pp

    post-processing (****post-processing).

    -fe_transfer

    FE transfer problem (****fe_transfer).

    -skin

    automatic mapping of 3D FE results on the surface mesh (****skin).

    -forge

    to read and concatenate two or more FORGE result files, to produce a single Z-set results database.

    -glue

    To glue/stitch subdomains’ results files into one file, after a parallel computation (****glue).

    -S

    run a simulation problem (****simulate).

    …

    other type of problems.

    -B file .mast

    run Zmaster in a batch mode.

    -zp

    run a Z-program script.

    Note

    In general, these switches are typically optional (except for -B). However, if several problems are defined in the same input file, the switch should specify which problem to be run. If problems of the same type are defined within a single input file, these switches can be combined with -N to specify the instance of the problem to run.

  4. Launch the graphical interface Zmaster

    -G

    run Zmaster GUI.

  5. Global parameters

    -s glob_param value

    modify the values of global parameters

    The list of global parameters and their default values can be printed using the switch -param_list or -v. For example, the Zmaster interface can be launched using wxWidgets toolkit with the command:

    Zrun -G -s Zmaster.Interface wx

    The value of several global parameters can be set using the syntax:

    -s glob_param1 value1 -s glob_param2 value2
