Dynamic implicit step is the only step of Abaqus/Standard solver which can be used to solve nonlinear dynamic problems.
In this tutorial, we will compare the results obtained by dynamic implicit and dynamic explicit steps.
Also the settings of the dynamic implicit step will be discussed in detail.
One of the most important issues in the post processing of the nonlinear dynamic problems is
the way of applying filter on the results to remove the numerical noise for better understanding and interpreting of the results.
In this tutorial, the Butterworth filter is used to filter the reaction force curve.
