Fuck Yeah Fluid Dynamics. Reader isotropicposts writes: Hi, I’m taking a fluids class and I’m not sure I understand the whole lagrangian-eulerian measurements of velocity and acceleration. Could you explain this? This is a really great question because the Eulerian versus Lagrangian distinction is not obvious when you first learn about it. If you think about a fluid flowing, there are two sensible reference frames from which we might observe. The first is the reference frame in which we are still and the fluid rushes by. This is the Eulerian frame. The other way to observe fluid motion is to follow a particular bit of fluid around and see how it evolves.
In the end, both reference frames contain the same physics (Einstein would not have it any other way), but sometimes one is more useful than the other in a given situation. Quantum Levitation.

E-mail: kotsoft@gmail.com Fluid Instructions: You can drag the fluid around with your mouse and adjust the sliders at the top to change the properties of the fluid in real-time.
Please check out this video if you're having trouble figuring out what the sliders do. It requires Java to run. Check out my newest app: Grantophone! More cool demos!

For interpolation, I use the quadratic B-spline presented here: Analysis and Reduction of Quadrature Errors in the Material Point Method. Instead of integrating the density over time (which is what most of the MPM papers do), I do a density summation every frame.
Material Parameters Some of these parameters are hard to explain in one or two sentences (and a couple I made up) so I'll also link you to their corresponding Wikipedia pages.
