Multi-fluid LOX tank pressurized by GHe

Objective: pressurize a liquid-oxygen tank with gaseous helium through a regulator — a multi-fluid network.

What you'll build

GHe → REG → LOX TANK, with helium on the pressurization branch and oxygen in the tank.

Steps

Assign GHe to the pressurization branch and LOX to the tank.
Set the regulator setpoint.
Mark each branch's fluid so the solver tracks them separately.
Solve.

Expected result

Ullage pressure ramps to the regulator setpoint while FSAP tracks helium mass consumed.
