On the effect of standard PFEM remeshing on volume conservation in free-surface fluid flow problems
A Franci, M Cremonesi - Computational particle mechanics, 2017 - Springer
The aim of this work is to analyze the remeshing procedure used in the particle finite
element method (PFEM) and to investigate how this operation may affect the numerical
results. The PFEM remeshing algorithm combines the Delaunay triangulation and the Alpha
Shape method to guarantee a good quality of the Lagrangian mesh also in large
deformation processes. However, this strategy may lead to local variations of the topology
that may cause an artificial change of the global volume. The issue of volume conservation …
