Introduction
A mesh is said to be dendritic if it contains elements with mid-side (edge) nodes when the predominant element topology has only corner nodes. A dendritic mesh is illustrated in Figure 1 where the predominant element is a four-node quadrilateral, but has also several five-node quadrilateral elements each with one mid-edge node plus four corner nodes. Such meshes arise when an approximately uniform element size is required across a mesh domain in cases, for example, where domain geometry changes would otherwise cause a significant variation in element size or in an Adaptive Mesh Refinement (AMR) context.
