Finite element simulation of full scale car crash based 100% on solid elements

[11myedu]

Is there anyway to make these simulation not with meshes but with particles?im not a expert in simulation but reply my question.

@11myedu No. We use particles to represent air, soil and high explosives in blast simulations, and SPH particles to represent water. But solid objects like in this video is best handled with finite elements. See through our other videos for examples of simulations done with particles.

What kind of model is imported?

@TheReasonWhyGuy The car is modeled entirely with solid (/brick/volume) elements. The front part consists of cubic elements, the rest with linear elements. At 0:15 you see the element lines and the region with cubic elements.

@IMPETUSAfea okay... not my area of expertise...

I make models using ordinary 3d modeling programs... and I have a feeling they wouldn't be importable... would I have to convert the file or, example a 3ds file, or would I need to make it (the model) in a native program :|

@TheReasonWhyGuy The triangle mesh you make is a boundary representation of the object. We don't use triangles as computational elements, but rather volumetric elements: tetrahedra, pentahedra and hexahedra. The car model is made of linear and cubic hexahedrons (linear hexahedrons has 8 nodes, cubic has 64 nodes and is extremely accurate). Converting a triangle mesh to a volume mesh is by no means straightforward...

How long did this render take??

[sambetty123]

hmmm, i like it

[Kitteh2006]

so the body panels are made out of latex?

@Kitteh2006 this is how a car crumples in a crash

cool
