Comments
- Available names are listed in the two
tables above.
In the first table, TH-variables are listed. If a TH-variable is requested, this variable is written.
In the second table, other variable groups are listed. If a variable group is requested, all the associated TH-variables are written at once.
- OFF:
- 0.0 deleted element
- 1.0 active element
- 2.0 (shells / solids): active element using small strain
- Negative value -1/-2 when the element is on stand by due to rigid body
Some intermediate values can be found during few cycles before element deletion (progressive reduction of off during a few cycles applies as a multiplicative factor to the stress, so that the stress is progressively vanished and element is deleted after ~ 10 cycles). This process applies to some element types, but not all.
