PAPP TPMS Filter — Schwarz P

This model is a deterministic TPMS-based porous filter generated with the PAPP protocol from a Schwarz P field and a balanced radial grading strategy. Compared with denser TPMS families, Schwarz P produces fewer, larger, and more direct flow channels, giving the structure a clearer cellular logic while preserving full topological closure. The final validated mesh is watertight and manifold, with 0 boundary edges, 0 non-manifold edges, and 0 degenerate faces. Topology audit: genus 268. Balanced…
