ANSYS Workbench Mechanical Dynamics
Accounting for the dynamic behaviour is often crucial in predicting a structure's integrity. Modelling the structures dynamic characteristics to investigate its influence on the response is therefore necessary. The different dynamic analysis types are covered. ANSYS functionality, commands, modelling of time dependent loads and structure characteristics together with results evaluation are aspects covered. Method for reducing analysis time, choice of solvers, mass representation and damping are among other topics.
