Explain the vorticity confinement method!
Restore missing vortices from the projection step
Explain the wavelet turbulence method!
take low resolution simulation, decomposit the frequencies, add desired turbulences for high quality advection
textures are also advected
Why do we lose energy in the regular velocity-pressure correction?
Because it is projected orthographicly which doesn’t preserve the length
Is there a vortex stretching term occurring in 2D?
No
What is the null space of the gradient operator? What is the null space of the (double) curl operator?
Gradient: constant
double curl: gradient of unknown scalar field
Which variable influences the Buoyancy in a smoke simulation? Temperature or smoke density?
Temperature
