Is there a way to use a mass flow rate source and define the pressure differential across a closed loop two phase pipe system?

Hi,

I'm trying to define flow through a two phase pipe using a mass flow rate source and to set the pressure differential in a closed loop pipe system using a pressure source along with a infinite flow restriction. But, I find that the model triggers an error exceeding maximum pressure limitations in the domain.

Any thoughts on this please.

Many thanks

Usually you may use source blocks to specify either the flow OR the pressure difference over a component. The resulting pressure drop or flowrate is then calculated based on the equations and parameters of the component. If you feel you have to specify both the flow and the pressure to replicate what you observe in the actual component, it's more likely that you don't yet have the actual parameters or physics of the component in the model yet.
