Validation Results

We don't just claim beastly performance; we prove it. Compare diTwoo's multiphase LBM solver against exact analytical solutions and legacy reference engines. Below is our verified ledger of standard physics benchmarks.

Test Context & Inputs

This test simulates steady, pressure-driven Poiseuille flow between two infinite parallel plates. We utilize our Adaptive Grid Refinement (AGR) framework to dynamically refine the mesh near the boundary layers, optimizing computational efficiency while preserving exact analytical accuracy.
