Description¶
In a fluid, fluid-FSI or fluid-solutes analysis, this boundary condition prescribes an elastic pressure \(p=R\,q+p_{d}\) on a surface, where R is the flow resistance and q is the volumetric flow rate across the surface (calculated internally); \(p_{d}\) is an optional offset pressure. The pressure p is converted to a dilatation and prescribed as an essential boundary condition at the nodes of the facets.
