59.54 GapFlow object

The GapFlow object specifies tangential flow constitutive parameters for pore pressure cohesive elements.

Access

materialApi.materials()[name].gapFlow()

59.54.1 GapFlow(...)

This method creates an GapFlow object.

Path

materialApi.materials()[name].GapFlow

Prototype

odb_GapFlow&
GapFlow(const odb_SequenceSequenceDouble& table,
        odb_Union kmax,
        bool temperatureDependency,
        int dependencies,
        const odb_String& type);

Required argument

table

An odb_SequenceSequenceDouble specifying the items described below.

Optional arguments

kmax

The string "NONE" or a Double specifying the maximum permeability value that should be used. If kmax="NONE", Abaqus assumes that the permeability is not bounded. This value is meaningful only when type="NEWTONIAN". The default value is "NONE".

temperatureDependency

A Boolean specifying whether the data depend on temperature. The default value is false.

dependencies

An Int specifying the number of field variable dependencies. The default value is 0.

type

An odb_String specifying the type of gap flow. Possible values are "NEWTONIAN" and "POWER_LAW". The default value is "NEWTONIAN".

Table data

If type=NEWTONIAN the table data specify the following:

Pore viscosity.
Temperature, if the data depend on temperature.
Value of the first field variable, if the data depend on field variables.
Value of the second field variable.
Etc.

If type=POWER_LAW the table data specify the following:

Consistency.
Exponent.
Temperature, if the data depend on temperature.
Value of the first field variable, if the data depend on field variables.
Value of the second field variable.
Etc.

Return value

A GapFlow object.

Exceptions

None.
