The Particle Finite Element Method (PFEM) is an appealing method for the simulation of highly deforming domains, as is the case for example in free surface flows. In PFEM, a new triangulation of the particles is required at each time step, creating a mesh on which the fluid equations are solved. To ensure a high quality mesh at all times and lower the cost of the triangulation operation, we propose a novel approach based on principles of constrained Delaunay triangulation. Simulations such as sloshing, droplet splashing and water column collapsing show the accuracy and efficiency of the method.
