Solving the Porous Medium Equation with the eXtreme Mesh deformation approach (X-Mesh)
Alexandre Chemin, Jonathan Lambrechts, Nicolas Moës +1
We introduce a new scheme for solving the non-regularized Porous Medium Equation. It is mass conserving and uses only positive unknown values. To address these typically conflictin…
