The fmesher geometry tool in the INLA package has several features that aren’t widely known. The code started as an implementation of the triangulation method detailed in Hjelle and Dæhlen, “Triangulations and Applications” (2006), which includes methods for spatially varying mesh quality.1 Over time, the interface and feature improvements focused on robustness and calculating useful mesh properties, but the more advanced mesh quality features are still there! The algorithm first builds a basic mesh, including any points the user specifies, as well as any boundary curves (if no boundary curve is given, a default boundary will be added), connecting all the points into a Delauney triangulation.
