Remarks and Examples

Remarks

Definition can be done by direct allocation of a number or a database entry or by linking several numerical variables. Variables make different commands (for example, STOP, OBJ_FUNC) much more flexible. A numerical variable can have the following status:
- NOT_CHECK: The variable is not yet determined.
- UNSET: The variable cannot be determined.
- SET: The value of the variable is determined and has been saved.
Only variables of TYPE DISP_X, DISP_Y, DISP_Z and ROT_X, ROT_Y, ROT_Z and REACTION_FORCE_X, REACTION_FORCE_Y, REACTION_FORCE_Z and REACTION_MOMENT_X, REACTION_MOMENT_Y, REACTION_MOMENT_Z and INTERNAL_FORCE_X, INTERNAL_FORCE_Y, INTERNAL_FORCE_Z and INTERNAL_MOMENT_X, INTERNAL_MOMENT_Y, INTERNAL_MOMENT_Z are admitted for COMBINE using SUB, SUB_ABS or VAR_OPER. Absolute displacements are not allowed for combination. Mean values of displacements can be calculated using this option.
The parameter VARIABLE can also be used to define operands for other VAR_OPER items. In this case, only two (or 2-4) entries are admitted, weights are not admissible, and their order is significant.
Plastic strain values (TYPE = STRAIN_PLASTIC) are calculated by Tosca Structure and might differ from your solver results.
