Boundary Layer meshing in CFD-VisCART

In order to accurately capture flow field characteristics, a fine mesh near boundary walls is often needed. This is commonly referred to as the Boundary Layer mesh or simply, Boundary Layers. When dealing with structured meshes, one would cluster grid points near specific boundaries before building mesh faces and blocks. But for an automated mesher, dedicated algorithms are needed to generate boundary layer cells. Both CFD-GEOM and CFD-VisCART are capable of generating boundary layer meshes, and they share the same core algorithm.
