====== Q2MLC ====== Mixed boundary condition for flow on 2D boundary ===== Description ===== **Q** (flow) **2**D **MI**xed **L**imit **C**ondition \\ The element imposes a fluid flow along the parabolic boundary of an element. This line is defined by 2 or 3 nodes. \\ {{:elements:tuyau.png?600|}} \\ The imposed flow is defined by law [[laws:qmlc|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. \\ \\ Type: 116 \\ Implemented by: J-P.
