LBM for shallow water

Is there somebody who has an experience with model of shallow water equations? I have a problem with stability.


There are some limitations of stability. They are really shortly described in this paper:
Lattice Boltzmann model for shallow water ?ows in curved and meandering channels
Haifei Liu, Guo Jian Zhou and Richard Burrows
International Journal of Computational Fluid Dynamics
Vol. 23, No. 3, March 2009, 209–220

Hopefully it will help,

Hi Alex,
Thak you. Now it wokrs ).

I have another problem in my algorithm. I wanted to use Guo force model in 1D model for SWE, which is described in the article linked below. I realy dont know why it doesnt work because it seems to be very easy. If somebody has some experience with that it would be very helpfull for me. I can provide all of my algorithms, if it is need. Thanks
