Comments

The syntax /H3D/ELEM/Keyword3/Keyword4/Keyword5 is also valid.
When PART IDs are listed after the /H3D/SOLID line the specified results will only be output for those parts.
To request integration point results, use /IR=i/IS=j/IT=k notation where the options can be entered in any order.
Option DAMG is only used with coupled damage models (such as /MAT/LAW72 or /FAIL/GURSON) to output damage over integration points. The damage variable is normalized by its critical value to get values between 0 and 1. For instance:
- For /MAT/LAW72
  $D_{m g} = \frac{D}{D_{C}}$
- For /FAIL/GURSON
  $D_{m g} = \frac{f_{t}}{f_{F}}$
If /NONLOCAL/MAT option is activated, it is possible to output the regularized non-local plastic strain and its rate.
The damage initiation variable /H3D/SOLID/DAMINI is used with some failure criteria such as /FAIL/INIEVO, which first computes a damage initiation criterion before computing the stress softening damage variable, which can be plotted with /H3D/SOLID/DAMA.
For failure criteria using different modes (mainly for composites), such as /FAIL/HASHIN, /FAIL/CHANG, and so on, these different modes can be output using the /H3D/SOLID/FAILURE option with the keyword MODE. You can choose to plot a specific mode using its number I (refer to the failure criterion documentation for mode number details), or all modes with ALL. The option MODE can be combined with LAYER and IR, IS, IT output keywords.
