Hi

I try to use do with two sided lid driven (i.e top and bottom lid). hence i gave the boundary condition as

- setBoundaryVelocity(lattice, Box2D(1,nx-1,ny-1,ny-1), Array<T,2>(u,0.));
- initializeAtEquilibrium(lattice, Box2D(1,nx-1,ny-1,ny-1),1., Array<T,2>(u,0.));
- setBoundaryVelocity(lattice, Box2D(1,nx-1,1,1), Array<T,2>(u,0.));
- initializeAtEquilibrium(lattice, Box2D(1,nx-1,1,1), 1., Array<T,2>(u,0.));

But there was no change in the bottom lid.

After that i tried with only bottom lid boundary condition.

- setBoundaryVelocity(lattice, Box2D(1,nx-1,1,1), Array<T,2>(u,0.));
- initializeAtEquilibrium(lattice, Box2D(1,nx-1,1,1), 1., Array<T,2>(u,0.));

still there was no change. please help me in this
