Hi,<\/p>\n
I believe I have made a post on here before. I am trying to use ANSYS LS-DYNA’s simulation capabilities to simulate concussions and other brain injuries. At this stage, the model can be quite crude. I just want to gain a basis level of understanding to build off of that allows me to see how the brain might move in the skull based on a given impact. I believe the brin has a high coeffcient of restitution, so even a little change in the angle or amount of force applied can affect the ways the brain moves or makes contact with the skull. These slight changes can create huge chnages in terms of patient symptoms of injury. I can use average brain sizes\/volumes and average skull sizes\/volumes to do this; I am not concerned about the effects of the neck at this time. Essentially, I want to see how a smaller spheroid with a very soft gelatin-like texture\/strcuture material moves inside a larger spheroid that is far more rigid. The gap between these two surrogate spheroids is known anatomically as the sub-arachnoid space, and is about 1\/4 inches. I was hoping to apply the force somewhat simply, using arrows or some type of vector, in a drag-and-pull sort of way. A good example of what I mean can be found here: https:\/\/phet.colorado.edu\/sims\/html\/collision-lab\/latest\/collision-lab_all.html<\/p>\n

I like this simulation, but it doesn’t allow me to reflect 3D-motion or put the objects inside one another. But the method of applying force is quite simple and is analogous to what I’m looking for.<\/p>\n
<\/p>\n
Now onto the ANSYS relevance… I have downloaded the own LS-DYNA package and the ANSYS Workbench which contains an LS DYNA mechanical module??? I am just really confused and overwhelmed by the capabilities of ANSYS and its intracacies. I see there’s an ANSYS Mechanical LS-DYNA as a part of the workbench, and a separate Pre-Post LS DYNA package along with a powershell. It’s just a lot. Could anyone help guide me on how to proceed in creating my model of the brain and skull– which can and should be crude in their geometrical design, though the consistency of the materials can hopefully be quite accurate– and how to simply apply force to this model. <\/p>\n
Also, I see that LS DYNA, the individual package NOT the mechanical module as a part of the workbench, has a head impact positioning feature. But it seems you may need to upload a model from somewhere else. I created two sphereoid objects in Pre-Post, but don’t know how to upload these into the head impact positioning feature, or if I even can\/should do that.<\/p>\n
<\/p>\n
Just really confused on how to proceed, I’m only 16. If anyone knows of any other simpler software that may be better for my purposes, I’m open to that. I just heard that LS DYNA has the ability to reflect biological tissues, like brain and bone, and the way the respond to force stimuli. <\/p>\n","protected":false},"template":"","class_list":["post-319855","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
