Abstract
For a variety of structural finite element analyses on automotive body panels, aerospace wings and space satellite panels, high-quality, structured quadrilateral meshing is imperative. Transfinite meshing, the technique to produce such meshes is severely infringed by the presence of surface-interior point constraints. The present paper attempts to solve the inverse problem of transfinite meshing with interior point cointraints. A modified Newton Raphson based solution is proposed to inverse solve Coons bi-linear blending equation. The Coons parametric coordinates are thus determined for a set of face-interior points from their global coordinates. The boundary of the surface is next seeded with soft-points at reflected locations and smart-discretized to result in high fidelity, high-quality transfinite meshes.
