hmtoggle_plus1Comments
1.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.

2.In case of co-rotational formulation for quad elements, the local stresses LSX, LSY, LSZ, LSXY, LSXZ, and LSYZ are given:
•for isotropic law in the co-rotational frame
•for orthotropic law in the orthotropic frame
3.SX, SY ... are the stress tensor components expressed in the global skew frame.
4.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.
