18.104.22.168 Fluid Resistance
In a fluid or fluid-FSI analysis, this boundary condition prescribes an elastic pressure on a surface, where is the flow resistance and is the volumetric flow rate across the surface (calculated internally); is an optional offset pressure. The pressure is converted to a dilatation and prescribed as an essential boundary condition at the nodes of the facets.
