.ThermofluidStream.Boundaries.Volume

Information

Conceptually a Volume is a Sink and a Source. It therefore defines the level of inertial pressure r in a closed loop and serves as a loop breaker.

This simple volume will become singular for incompressible fluids and close to singular for fluids with very low compressibility. For both cases we advise to use VolumeFlex or a Reservoir instead.

Since there is no formula to compute density_derp_h for this volume, an upper bound has to be set in the parameter density_derp_h_set. Alternativeley the derivative can be taken from the media model for all the media that implement the corresponding formula by setting density_derp_h_from_media=true (default:false).
