ParaMetal

This project allows the visualization of heat transfer between two or more 3D closed surface geometry. The simulation is deterministic, transient and operates in realtime using stable pre-processing methods.

The major pre-processing methods include an intrinsic remeshing operation that preserves the shape of the geometry and a meshless restricted voronoi diagram step that discretizes the volume of the surface boundary.

This project is a work in progress. Functionality, performance and physical accuracy will be continuously updated.
