pyva.coupling.junctions

This module deals with the physics of junctions

In contrast to connections the junction classes deal with the physics and the degrees of freedom/wavefields of the coupling.

The abstract junction class pyva.coupling.junctions.Junction is extended by classes with specific geometry, namely:

• pyva.coupling.junctions.LineJunction Plate line junction

• pyva.coupling.junctions.AreaJunction Cavity-plate junction

• pyva.coupling.junctions.HybridAreaJunction Hybrid cavity-FEM(surface) junction

• pyva.coupling.junctions.SemiInfiniteFluid Fluid half space junction
