Orthogonalization
Grid orthogonality is fundamental to accurate domain simulation — poor orthogonality introduces numerical errors that compromise model results. Grid+ lets you minimize orthogonal deviation across your entire domain or within targeted sub-regions.
Demonstration of global orthogonalization of a grid.
Global Orthogonalization
With a single click, Grid+ optimizes orthogonality across the whole model domain, eliminating hours of manual adjustment. The results are dramatic: in the example shown, average orthogonal deviation drops from 7.43 to just 0.25 — a 97% improvement in one step.
Local Orthogonalization
For problem areas needing focused attention, Grid+ lets you target any user-defined region for refinement using a suite of advanced optimization algorithms, including methods comparable to those in RGFGrid.
