moving boundary and LBM-DEM coupling

Dear everyone,

 Any people here  are interested in coupling of LBM and DEM ? 

 Any people  tried the boundary condition of  D R Nobleand JR Torrczynski ( int j mod phys, c, 9:1189-1201, 1998 ) ,

  or  B.K. Cook ( engineering computations, 21:151-168,2004),

   or Y T Feng ( int j numer method engrg 72,1111-1134,  2007)     ?   

I 'd like to communicate with you.
