This option is used to define leak-off coefficients for pore pressure cohesive elements.
Products: Abaqus/Standard Abaqus/CAE
Type: Model data
Level: Model
Abaqus/CAE: Property module
Set this parameter equal to the number of field variable dependencies included in the definition of the fluid leak-off coefficients, in addition to temperature. If this parameter is omitted, it is assumed that the leak-off coefficients are constant or depend only on temperature. See “Specifying field variable dependence” in “Material data definition,” Section 21.1.2 of the Abaqus Analysis User's Guide, for more information.
Include this parameter to indicate that user subroutine UFLUIDLEAKOFF will be used to define the fluid leak-off coefficients.
First line:
Fluid leak-off coefficient at top element surface.
Fluid leak-off coefficient at bottom element surface.
Temperature.
First field variable.
Etc., up to six field variables.
Subsequent lines (only needed if the DEPENDENCIES parameter has a value greater than six):
Seventh field variable.
Etc., up to eight field variables per line.
Repeat this set of data lines as often as necessary to specify K as a function of temperature and field variables.
