Web22. sep 2024 · The remeshing technology automatically creates new crack faces, refines the mesh at the crack-front, and coarsens the mesh in other regions to maintain accuracy while maintaining minimum mesh count. Both NLAD and S.M.A.R.T are useful solver-based remeshing techniques. WebThe mesh contains about 275 nodes. The mesh near the corners is particularly coarse--the mesh generator produces little refinement, since the input geometry meets the mesher's minimum angle constraints.
