Web13 Jan 2016 · snappyHexMesh: limited region-based refinement The refinement, i.e. edge-based, surface-based or volume-based, can now be limited to geometric regions using the … WebThe ISIS solver of the FineTM/Marine package is used to solve the flow problems. An adaptive mesh refinement is employed for resolving the flow inside the areas hosting significant flow gradients. Two sets of computations are analyzed: one refers to the straight-ahead course, whereas the other is focused on the static drift motions.
