Event Simulation technical info on mesh and solver?

[tony.sadaka]

Hello, 
I am a Masters student in mechanical engineering and I am currently working on my thesis and need to perform explicit FEA. I was looking at Fusion's Event Simulation for impacts and I need to know the technical details about the mesh and solvers that are being used and if it is possible for me to pick my own element type or order. I believe the element being used in the simulation workspace is Tet10? Im not sure about that but hopefully I can pick my own. 

I am hoping there is some documentation about the solver and mesher being used I can reference or look into so I can validate my results when comparing with other packages.

I appreciate any help, thank you!

Hello @tony.sadaka

Regarding the mesh elements. In Fusion 360 you can use only tetrahedrons (Tet4 and Tet10 or else, elements with linear/parabolic shape function). It is intended because this type of element allows you to discretize almost every geometry (especially free form shapes), using the automatic mesher. You are not able to modify the type of element in your own way.

Event simulation is a specific type of simulation because it uses explicit solver which doesn't require achieve an equilibrium (there is no need to reach convergence each increment), unlike other analyses with implicit solver. 

If you want to better understand how explicit works and what events it computes the best, please see technical documentation of Fusion 360 simulation and Autodesk Nastran:

Here is another link to the webpage where you can deep dive into differences between implicit and explicit solver:
