This lesson covers four parts aimed at enhancing your simulation skills in Ansys Discovery. The first part guides you in working with bigger, multipart assembly, updating physics conditions, and optimizing geometry for efficient solution. Part two focuses on creating idealized bolt elements and solving with bolt pretension. We will also create hinged connections for the simulation. The third part demonstrates how to work with contact definition and all the aspects associated with it. Lastly, the fourth part explores running solutions in the Refine stage, utilizing Ansys Mechanical's flagship solver for advanced physics and meshing controls.
