In this quick demo, we import a drone STL, let Stallion 3D auto‑configure the CFD boundaries and domain sizing, pick a sensible default mesh, and run the solver—going from geometry to pressure contours in minutes.

What the video covers Import geometry via Design → Import STL (ASCII or binary). Set units (e.g., meters) and position/orientation. Automatic domain & boundaries: Stallion 3D sizes the CFD box and boundary conditions from the STL—so you don’t have to hand‑tune the grid extents. Optional geometry quality check: If your STL has gaps/holes, run the quick check to mitigate issues before grid generation. CFD setup with smart defaults: choose a mesh density (Quick, Medium, Large; example shown: ~1 M cells). The default solver and domain dimensions are good starting points. Generate & solve: Start meshing and the flow solution in one click. Visualize results: View the 3D geometry and pressure distribution; add legends/units (Pascals) with the graph options.

Why this workflow is fast No manual domain sizing—it’s solved by default. Defaults that “just work” for early design checks. Applies across subsonic, transonic, and supersonic regimes for rapid concept iteration.
