Welcome to Lautsch Finite Elemente GmbH. We focus on the development of the Multigrid Marching Tetra Method for automatic meshing of 10 000 parts, and more. The two sides of the Brandenburg Gate showing an exaggerated movement in an Eigenform. This website collects posters, PDFs and links to support the development of the Multigrid Marching Tetra Method. Poster Poster MULTIGRID MARCHING TETRA Poster MULTIGRID for linear Systems Poster Why tetras do not work PDFs - The Multigrid Marching Tetra Algorithm - Eigenforms of the Brandenburg Gate - Knife - Is there any cubic simplex in 4D space ?
