The interface between SANS and Pointwise is a fine-grain point cloud of sizing requests that drives the Pointwise meshing algorithm. Viscous adaptation is achieved via a hybrid approach where sizing requests drive isotropic refinement and viscous layers are apriori generated. Adaptation results are shown for L_2 projection of a corner singularity solution in both 2D and 3D, as well as adaptation for both inviscid and viscous airfoil cases starting from extremely coarse initial mesh resolution.
