LFLUID
A linear fluid monitored volume which models a volume filled with fluid.
In the LFLUID monitored volume, the density and bulk modulus of the liquid are defined. There are optional curves to define the mass flow rate in and out over time. The bulk modulus can also be defined as a function of time.
Additional pressure can be included by defining a function for the pressure added versus time. Lastly, the maximum pressure in the volume can be defined.
