I’m interested in trying to simulate blood pooling in the lower legs. My thoughts were to change right/left leg vasculature volume or pressure, and decrease the outflow, but I don’t see a clear way to do this. Is it possible to do this, or is there an alternative way to simulate blood pooling in the legs? Thanks!

You can try to increase the [resistance to this path](https://gitlab.kitware.com/physiology/engine/-/blob/stable/src/cpp/engine/common/controller/SetupCircuitsAndCompartments.cpp?ref_type=heads#L771) in CardiovascularModel when you want to start the pooling process.
That will increase the pressure in the leg, which will add volume to the compliance

Probably want to decrease the resistance for the inflow to the leg as well. Line 766 in the link Aaron supplied.
