Description

The keyword $TRANSFER_COEFFICIENT enables to specify the mass transfer coefficient between two continua in a dual continua model. This keyword can be used in the process Richards flow (dual continua).

Parameters

In the following example, a transfer coefficient of 500 (1/m²) is given to specify the mass transfer between the matrix continuum and the fracture continuum in a model describing fluid flow in densely fractured rock.
