Web22 okt. 2024 · The answer is the nonlinear adaptivity (NLAD) feature in Ansys Mechanical. The tool automatically repairs the mesh distortions that trigger convergence issues under large deformations. From there, the tool refines the mesh as it distorts to ensure local phenomena are captured correctly. How to Remesh Geometry Under Large Deformation WebWith such an elastic model, the only solution to decrease these deformations has been so far to increase the stiffness of the deformed springs, but we show that it dramatically increases the cost of the algorithm.
