A Parametric Patch Surface Geometry Definition for the Three-Dimensional Retarded Potential Technique.

reportActive / Technical Report | Accession Number: ADA182223 | Open PDF

Abstract:

A parabolically parametric surface patch basis has been developed for the geometric calculations of the discretized retarded potential integration. Arbitrary three dimensional surface geometries can be handled, with a present restriction on the allowed orientation of the surface patch grid lines. A test problem confirms the accuracy of the formulation. Keywords Retarded potential integral Boundary element method Acoustic wave Parametric surface geometry Differential geometry.
