Solver

The ramp raises the inlet speed smoothly from rest; it avoids the pressure pulse of an impulsive start. The GPU solver needs WebGL2 with float render targets; the CPU solver is used otherwise and is marked in the status bar.

Physical scale

Used for the physical read-outs (Δx, Δt, forces per metre of span) and for the “Set Re from these” button in the Flow section. The Reynolds number set in the tunnel is what the solver runs.

Import an SVG outline

Open an SVG file or paste the d="…" data of a <path>. Curves are sampled into segments, the outline is scaled to the chord and the flow comes from the left. M, L, H, V, C, S, Q, T, A and Z commands are supported.
