With ALE adaptive meshing, typically something in between a fully Eulerian and fully Lagrangian analysis is used: the material deforms with respect to the mesh, and the mesh deforms as well: the ... WebMesh reduction using algorithms, such as vertex clustering to remove vertices least affecting properties of the original mesh, can be dangerous as they may not necessarily guarantee preserving topology. A simple work-around is to alternate the smoothing and split-and-merge algorithms so the topology is preserved whilst the mesh is being smoothed. gregg\u0027s ranch dressing ingredients
