Information

Unit test for Elbow. The bend radius is ramped so the relative bend radius rc/D sweeps from 0.5 to 2.5 during the run. Two parallel circuits are exercised: from_dp is pressure-driven and from_mflow is driven by a sinusoidal (sign-changing) mass flow rate, verifying both the loss magnitude and correct flow-reversal behaviour.
