Resource Abstract

The idea of automatic meshing did not end with the emergence of Delaunay meshing in the 1990s. The most challenging question today is: How to mesh an arbitrary number of parts and automatically create a mesh of the impacting surfaces.



We present a method, which sucks to the surfaces iteratively by the rule “bisect edges which hit a surface”. It is very close to the classical Multigrid Meshing Method but the last step is a Marching Tetra refinement. Looking more closely to this step, it reveals to be a special Multigrid refinement.



The Marching Tetra method is designed for the vehicle thermal management process for passenger cars.
