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.

parent_gray

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:

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
  2. GrainCount
  3. 1_CrystalliteCount
  4. 1_texture
  5. 1_1_orientation

Legacy format

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