Navier Stokes algorithm 2D abnormal behaviourHi, I am beginner to CFD and trying to replicate the Navier Stokes effects by copying below whole algorithm into Java....
Youtube link (2 short slide; up to 39:56): http://www.youtube.com/watch?feature...shXhWU#t=2275s It solves for b[i,j] and then get pressure[i,j] using poisson equation. Using p[i,j], it then solves for velocity[i,j] The above steps is repeated many times to produce this dynamics. But when I simulate by setting initial velocity[5,5] = 0.1 and run the program, pressure & velocity nearby just grows bigger quickly to infinity. Actually is there any problem with her algorithm? Is it wrong? :confused: |
