How to reduce oscillations in a graphic
I have a question for you.
When I see the result of my simulation, the graphic of the strain rate, has a lot of ascillations.
My question is: What do I have to do in order to avoid or reduce the oscillations?
I attached my graphic to clarify better.
Thanks in advance
There are quite a few things at play with oscillations like this. Explicit vs Implicit, the type of element you are using, the element formulation, hourglass, and even the material itself can all impact this.
Sometimes there really isn't much to do if you aren't willing to change the fundamentals of your model. In this case, you can just apply a conservative filter and report the data as so.
