I want to implement staggered grid in the 3D fluid simulation. There is little resources talking about it, especially in the web. I can't afford to a hardcopy of a book. Any thread is appreciated. Detail presentations are prefered.

Well, check out "Visual Simulation of Smoke" by Fedkiw et al.

It's a rather easy-to-read paper which uses staggered grid for the velocity field.

Anyway, once you understand the idea, it should be straightforward to implement.

Here are some links to papers online. I have not opened them, and cannot speak to how useful they will be. Most likely they are advanced, but might help a bit in combination with Fedkiw's stuff (referenced by uutee).

Thank you both!

Actually my implement is according the paper "Visual Simulation of Smoke". In the advection step using staggered grid confuse me. I cann't get a clear view on how to interpolate and use semi-lagrangian scheme in the staggered form. Alway need to use (a+b)/2 liked code or maybe tri-linear interpolation to get the value I need. The advect code is also hard to reuse, since for every directions the code differ a little bit almost in all lines.

In CFD Online, I found some related topics. I'll read them and the paper "Computation of compressible flows on unstructured staggered grids" for more understanding.

Btw, it's my first time to get into the CFD kingdom. If I act some ignorance, tell me. :O) Happy New Years!
