Using Adaptive Convergence with Ansys Mechanical*

Ansys Mechanical can solve a variety of complex real-world mechanical problems. But how do you know about the accuracy of the solution? Is there a rule to decide the level of accuracy of the solution? In this video, we will answer these questions using Adaptive Convergence. It helps you get mesh-independent solutions such that the results don’t change noticeably with further mesh refinement. This can help you to define better mesh controls for future models to ensure numerical accuracy. For free courses offered through Ansys Innovation Courses visit http://www.ansys.com/courses.
