Figure 2 demonstrates a simulation of a bird strike on a turbine.ДЇigure 2: Example of Automatic Contact Tracking One of the most versatile features of the contact detection algorithm is that it will automatically rebuild the surfaces of the model as material erosion occurs and new surfaces are exposed due to element deletion.

Autodesk Explicit constantly monitors and tracks the proximity of the various free surfaces of the model though all the large deformations and rotations to enforce the kinematic compliance of the parts when collisions are detected. There is no limit on the number of parts that can contact one another and very little effort is required by the user.ДЄt most, the user specifies friction behavior between the different parts (default friction coefficient is zero) or specifies that the contact surfaces are welded together (default behavior is non-welded/separable surface pairs). You simply define all the parts that make up your assembled model and the application will automatically monitor the collisions between the parts and enforce kinematic compliance. We will see that the explicit algorithm requires a relatively small time step, so it is extremely important that the cost of each times step is low.Д¬ontact modeling is very straightforward within the explicit dynamics technology. In a nutshell, not having to solve large systems of algebraic equations means a small memory footprint and each time step is extremely efficient to compute. The key enabler is that there is no assembled system of algebraic equations that must be solved for each time step as you find in traditional implicit finite element formulations.ДЄn explicit solver simply forms the dynamic equilibrium equations for the finite element model at each instance in time and uses an explicit integration rule to march forward in time. The explicit dynamics procedure is ideally suited for simulating extremely large models regardless of how nonlinear the problem might be. The user has no 'convergence' settings to tweak, as is necessary for linear solvers, and simply launches the simulation without regard for the linearity of the system. In general, performing nonlinear explicit simulations is often simpler than performing linear simulations.
