Sorry, just to clarify, I would like to state that the brain is encased in cerebrospinal fluid which fills in the aforementioned subarachnoid space. The cerebrospinal fluid be assumed to be water and have all the same properties, as it is 99% water.

 

If it is much simpler to not account for the brain's 'floating' in this fluid then I won't. It could be just assumed to be an empty space/gap between the the skull and brain (AKA to spheroid objects). I have attached sceenshot photos that help explain the above post further.

These videos contain head models, though I'm not sure if they contain a brain. Am I able to access these models publically and easily or do I have to create them myself? In either case, would I do so in the LS DYNA Pre-Post or the ANSYS LS DYNA Mechanical module as a part of the general workbench?

 

Other things worth mentioning, if not able to simply apply force/velocity/accerleration vectors like I am able to in the post's linked simulation, I could make the force come from making the head come into contact with a wall, another head, or just a cube, all being solid, rigid bodies. Injurous brain movement/concussions normally occur at around 60-100 Gs of force, for reference. 

 

I don't need to see in-depth analysis of the brain's injury to neurons or anything like that, just a way to gain a basis of understanding for how the brain might move in the skull in high-force collisions/impacts, on a MACRO-level. I'm hoping to create graphs of the brain's movement, and/or force (acceleration and velocity graphs) from the data I collect. I believe ANSYS can create these graphs but I'm not sure how to do so.

 

Thank you for your time!
