2.1.21. marc_addUserOutput


Purpose

Transfer the output variables requested in the material.config to properly labelled user-defined variables within the Marc input file (*.dat). Requires the files .output<Homogenization/Crystallite/Constitutive> that are written during the first run of the model. Specify which user block format you want to apply by stating the homogenization, crystallite, and phase identifiers. Or have an existing set of user variables copied over from another *.dat file.

Usage

> marc_addUserOutput options option(s)

--homogenization [ 1 ]
homogenization name or index
--crystallite [ 1 ]

Examples

Plain numbered user outputs

In case you
  • already know the exact number of user outputs that will be produced from all active (output) entries in the material.config file
  • do not need descriptive names of user output variables
you can use the --number option to prepare the input deck file.

> marc_addUserOutput --number 5 jobname.dat

The file jobname.dat is altered to contain five extra lines in the "post" section:
post
...
        -1         0
        -2         0
        -3         0
        -4         0
        -5         0

Transfer from material.config

The usual way of operation is to tell the script which section from the homogenization, crystallite, and phase part of the material.config should define the user data block.

Suppose we have such a (abridged) material configuration:
#------------------
<homogenization>
#------------------

[SX]
type    isostrain
Ngrains 1

...

#-----------------------
<crystallite>
#-----------------------

[one]
...

[two]
...

[small]
(output) texture
(output) orientation
(output) grainrotation
(output) f
(output) p

...

#-----------------------
<phase>
#-----------------------

[first]
...

[CP_phenopowerlaw]
(output)                resistance_slip
(output)                shearrate_slip
(output)                resolvedstress_slip
(output)                totalshear
lattice_structure       fcc
Nslip                   12 0  0 0

...
During the initialization of the corresponding simulation, the above mentioned three jobname.output* files will be produced. Once they are present, it is possible to use this information to alter the jobname.dat file by issuing
> marc_addUserOutput --homogenization 1 --crystallite 3 --phase 2 jobname.dat
which will add these 68 entries to the post section of the input deck:
