Comments

  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. Only one nstrand element is allowed for the group.
  3. Within a group, two xelem_usr must not be equal.
  4. Both xelem_usr and xelem_name appear in the Time History.
  5. 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.
