Advanced Numerical Methods for Nonlinear Dynamics

With a solid foundation of element and material technology, ANSYS Explicit dynamics solutions offer various advanced solver technologies to best simulate a comprehensive list of dynamic applications. The multiple solution methods described and pictured below can be combined in several ways through the use of part interaction. The interactions can be through contact, bonded contact and coupling between Euler and Lagrange regions for problems involving fluid–structure interaction (FSI). For parts that interact via contact, the contact surfaces that are automatically redefined as elements on the surface are removed through erosion. The table below shows the solvers that are available with each of the three explicit dynamics products, through the ANSYS Workbench interface.
