Описание: This video lesson shows that explicit time integration works best for fast events like a car crash or a bullet impact that occur in the range of milliseconds to seconds. The implicit method works better for slower events like material creep or gear intermeshing, which can take place in the range of minutes to days. In general, the time-step size is limited so that a stress wave cannot travel farther than the smallest element characteristic length in a single time-step. This lesson is part of the Ansys Innovation Course: Time Integration.
