Optional parameters
- HEAT
-
This parameter is relevant if there are regions in the model that use coupled temperature–pore pressure elements; it specifies whether heat transfer effects are to be modeled in these regions.
Set HEAT=YES (default) to specify that heat transfer effects are to be modeled in these regions. In this case Abaqus/Standard solves the heat transfer equation in conjunction with the mechanical equilibrium and the fluid flow continuity equations.
Set HEAT=NO to specify that heat transfer will not be modeled in these regions.
This parameter is not relevant if only coupled pore pressure–displacement elements are used in a model.
- UTOL
-
This parameter will invoke automatic time incrementation.
Set this parameter equal to the tolerance for the maximum change of displacements. Abaqus/Standard will ensure that the maximum absolute value of a displacement at a node is smaller than the tolerance times the characteristic element length in the model. If this parameter is used without any value specified, the default value of 10−5 is used. If this parameter is omitted, no restrictions are imposed on the displacement values.
Data line to define automatic time incrementation
- First (and only) line
Initial time increment. This value will be modified as required. If this entry is zero or is not specified, a default value that is equal to the total time period of the step is assumed.
Time period of the step. If this entry is zero or is not specified, a default value of 1.0 is assumed.
Minimum time increment allowed. If Abaqus/Standard finds it needs a smaller time increment than this value, the analysis is terminated. If this entry is zero, a default value of the smaller of the suggested initial time increment or 10−5 times the total time period is assumed.
Maximum time increment allowed. If this value is zero or is not specified, no upper limit is imposed.
