Don’t hesitate to ask any questions you might have about the explanations presented in this video using the comments below. We try to answer all questions regarding the video details in the comments below.

Sources of nonlinearity in structural mechanics simulations:
- Material nonlinearity
- Boundary nonlinearity
- Geometric nonlinearity
Types of dynamic analysis:
- Linear: non of the sources of nonlinearity are included in the model like Frequency analysis
- Nonlinear: one or more sources of nonlinearity are included in the model like Crash, Explosion, Ultrasonic process, Machining process analyses
To compare the results of linear and nonlinear dynamic analyses, two types of problems will be solved:
1) Geometric nonlinearity is not included (Nlgeom=off)
2) Geometric nonlinearity is included (Nlgeom=on)
We will solve a problem using both procedures and compare the results. Moreover, the effect of the displacement value on the difference of the results will be investigated.
In the following tutorial, I will solve the model using the Dynamic Implicit step and compare its results with the results obtained by the Dynamic Explicit step.
Also, the necessity and the procedure of applying a filter to the obtained results (to remove the numerical noises) will be discussed in detail.
