Скачать или смотреть Restarts in Ansys Mechanical

This video shows how restarts can be utilized in Ansys Mechanical to start from a previously solved substep and change things like load step settings and nonlinear stabilization energy in order to achieve convergence in a snap-through nonlinear buckling analysis. Taking advantage of restarts allows users to save time and effort relative to solving the model from scratch. For more information on applications and limitations of restarts in Ansys Mechanical, see our blog post below:
