An overview of the "universal mesh" algorithm for creating quality simplex meshes of implicitly-defined regions.
A reference containing information about periodic surfaces suitable for infill structure in 3D printed parts.
Different methods of enforcing simple constraints on ODEs can impose additional stability criteria.
This document investigates the effectiveness of multigrid when used on a nonconforming hierarchy of unstructured meshes.
An algorithm for coarsening simplex meshes, to enable multigrid methods with unstructured meshes.
A simple iterative procedure for improving element quality of finite element meshes.
Gauss is said to have found an elegant visual proof for summing integers. Does a similar idea work for summing perfect squares?
What sound does a coffee mug make when you tap it with a spoon? In this post, we write a small 2D finite element code in Mathematica to simulate a coffee cup vibrating.
