Spatial Mesh Engine is a modern C++20 + Python framework for Finite Element Analysis (FEA) and computational geometry. It's the open-source alternative to ANSYS, COMSOL, and commercial FEM software—built for engineers, researchers, and students who want production-grade analysis without enterprise price tags.
