Preamble

DAMASK reports at each material point (= integration point in the case of FE solvers) outputs that have been requested through the material configuration for the active homogenization and for each constituent grain.

Structure

This block of data is structured into two parts
  • homogenization output
  • grain(s) output
    • crystallite output
    • constitutive output
Each (sub-) part has as first entry its item count followed by the actual data. The overall format is as follows:

part variable
homogenization N
homogenizationResult #1
...
homogenizationResult #N
grain M
1 R
crystalliteResult #1
...
crystalliteResult #R
C1
constitutiveResult #1
...
constitutiveResult #C1
2 R
crystalliteResult #1
...
crystalliteResult #R
C2
constitutiveResult #1
...
constitutiveResult #C2
... ...
... ...
M R
crystalliteResult #1
...
crystalliteResult #R
CM
constitutiveResult #1
...
constitutiveResult #CM

Example

Consider this material configuration to be selected for a simulation:
#-------------------#
<homogenization>
#-------------------#

[SX]
type   isostrain
Ngrains   1

#-------------------#
<microstructure>
#-------------------#

[SX_cube]
crystallite 1
(constituent)  phase 1   texture 1   fraction 1.0

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

[essential]
(output) texture
(output) orientation
(output) grainrotation  # deviation from initial orientation as axis (1-3) and angle in degree (4)
(output) f              # deformation gradient tensor; synonyms: "defgrad"
(output) p              # first Piola-Kichhoff stress tensor; synonyms: "firstpiola", "1stpiola"

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

[Aluminum_phenopowerlaw]

constitution            phenopowerlaw

(output)                resistance_slip
(output)                shearrate_slip
(output)                resolvedstress_slip
(output)                totalshear
...
...

The following data block of 68 items would result from that material configuration:
  1. HomogenizationCount

Legacy format

Until revision 1115 of DAMASK the grain count, M, has been stored as the first entry, i.e., before homogenization count N.
