I am working on a structural adapter and I’m experimenting it with some of the tutorials. When simulating something like the vertical flap with SU2 euler flow, I obtain something like the video below, which at least qualitatively looks physically reasonable:
Going into the data of the simulation, I recovered the data from the interface mesh and imported them together with the fluid flow. During some timesteps find situations like the one below:
Pressure is about 1 bar around the flap, which is 1m tall, divided into 40 segments. Sometimes the x component of the interface nodal forse is as plotted: positive on the right and negative on the left, which seems odd. Besides the nodal force is much lower than what I would expect (approx 10e5/40). Am I missing something?
