Sorption(...)

This method creates a Sorption object.

Path

mdb.models[name].materials[name].Sorption
session.odbs[name].materials[name].Sorption

Required arguments

absorptionTable

A sequence of sequences of Floats specifying the items described below.

Optional arguments

lawAbsorption

A SymbolicConstant specifying absorption behavior. Possible values are LOG and TABULAR. The default value is TABULAR.

exsorption

A Boolean specifying whether the exsorption data is specified. The default value is OFF.

lawExsorption

A SymbolicConstant specifying exsorption behavior. Possible values are LOG and TABULAR. The default value is TABULAR.

scanning

A Float specifying the slope of the scanning line, (d⁢uw/d⁢s)|s. This slope must be positive and larger than the slope of the absorption or exsorption behaviors. The default value is 0.0.

exsorptionTable

A sequence of sequences of Floats specifying the items described below. The default value is an empty sequence.

Table data

If lawAbsorption=TABULAR or lawExsorption=TABULAR, the absorptionTable and exsorptionTable data respectively specify the following:

  • Pore pressure, uw.

  • Saturation, s.

If lawAbsorption=LOG or lawExsorption=LOG, the absorptionTable and exsorptionTable data respectively specify the following:

  • A.

  • B.

  • s0.

  • s1.

Return value

A Sorption object.

Exceptions

RangeError.

setValues(...)

This method modifies the Sorption object.

Required arguments

None.

Optional arguments

The optional arguments to setValues are the same as the arguments to the Sorption method.

Return value

None.

Exceptions

RangeError.

Members

The Sorption object has members with the same names and descriptions as the arguments to the Sorption method.
