The Limitation of VLM
Traditional Vortex Lattice Methods model lifting surfaces as infinitely thin plates. While computationally cheap, they fail to account for:
- ✕ Leading edge suction peaks on thick bodies
- ✕ Displacement effects of fuselages
- ✕ Accurate 3D pressure distributions
How VSM Works
Unlike VLM, which places singularities on an idealized mean‑chord surface, the Vertex Singularity Method (VSM) distributes vorticity and source strength directly over the full 3D surface mesh. By enforcing the boundary condition on the actual geometry, VSM captures the true volumetric influence of the body rather than approximating it as an infinitely thin lifting surface.
Surface Fidelity
Directly utilizes STL/CAD vertices to define the flow field boundaries.
Real-Time Solver
Matrix inversion optimized for parallel GPU processing architecture.
Computational Efficiency
The Neumann Platform leverages a meshless-style approach that bypasses the traditional RANS volume meshing phase. This reduces the "time-to-insight" from hours to seconds. In this approach, the mesh serves only as a lightweight computational scaffold; it does not control numerical accuracy. Instead, the solver operates directly on the faceted surface geometry, making geometric fidelity the primary determinant of solution quality. Because the analysis is performed on the surface representation itself, the accuracy of the results is directly tied to the resolution and quality of the underlying geometry.
