Running a steady-state solve

With your boundary pressures fixed, press Solve (⌘/Ctrl + R). The Newton-Raphson iteration drives the mass, momentum, and energy residuals toward your tolerance.

Watch convergence

The residual plot updates live. The default tolerance is 1e-9; if a network won't converge, FSAP reports which residual is largest so you can find the unconstrained node or bad input.

From the CLI

$ fsap solve my_network.fsap --mode steady
