I was talking to my father in law (head of particle research for P&G) about particle simulation for research purposes and he was explaining the complex challenges with behaviour of interactions. It amazes me that even at the mathematical level, a post-doctorate doctor of chemical engineering with a team of physicists/computer scientists/mathematicians/chemists are still facing challenges which Disney seem to have solved - glad to see they are properly releasing this research!
- fsloth 13y agoThe requirements for a visual simulation and industrial process simulations are quite different.
- NamTaf 13y agoThis process yields fantastic, realistic visuals, but I bet you'd find it does not yield the scientific information they're chasing. It's sort of like how the 'standard' linear static finite element method assumes insignificant displacements and no plastic yielding of materials - as soon as you need to deal with any sort of significant level of displacement or distorsion of the material in question, a linear static solver isn't capable of giving you accurate results. With displacement, it tries to fake it by extrapolating the linear displacement and assumes that applies over the entirety of it, when in actual fact as soon as it displaces, the strain field in the material will change and it needs re-solving. It's a good tool, but it has its limitations.
