What I mean by body-body load transfer:
Well, normally objects (particular parts of geometry in assembly) don’t “see” each other. You have to point regions where objects meet/interact. For instance let’s take two boxes and name them A and B. We put them on the ground so they stay next one another. They are separate geometries and there is no contact between them. Now, Box_A is fixed to the ground. Box_B however is being pushed from one side in the Box_A direction. If there is no contact defined Box_A will be “invisible” to Box_B therefore Box_B will go through Box_A. What I’d like to have (as a feature/function) is automatic clash (conflict) detection between those two boxes - as you have in computer games’ engines.
It is also present in CAD systems and used to identifying errors in assemblies.
Theoretically you already have this function or it will be available soon in crash test cases. This is very good example of what I’m writing about. You don’t define contact regions between objects and they still interact. And it works.
I’m aware this approach is more demanding numerically than just standard static FEA, but I think it could be used many times improving accuracy - in large deformation cases for instance, where due to big displacements additional contacts may occur.
Moreover, if you mastered it this solution is ready for CFD with overlapping meshes!
I know such approach makes simulations available for people with very little knowledge and experience, but on the other hand professionals would welcome it heartily. It would make their work easer and allow them to perform more advanced simulations with smaller margin of error due to less model simplifications.
I hope you get the point :-)
