Q2MLC
Mixed boundary condition for flow on 2D boundary
Description
Q (flow) 2D MIxed Limit Condition
The element imposes a fluid flow along the parabolic boundary of an element. This line is defined by 2 or 3 nodes.
The imposed flow is defined by law QMLC. The retention curve allowing the distribution of the total flow between a water flow and a gas flow depending on the saturation is also given by this law. The total flow is multiplied either by FMULT or by DMULT.
