Hi @mohdafeefbadri,
welcome here! Yes you can make the road surface a moving boundary. Two steps to do this: enable the MOVING_BOUNDARIES
extension by uncommenting the linked line, and in the main_setup()
function, set the boundary flag for the bottom cells if(z==0u) lbm.flags[n] = TYPE_S;
and make the velocity in this bottom layer non-zero: if(z==0u) lbm.u.y[n] = lbm_u;
See the F1 car sample setup and FluidX3D Documentation for details. Note that there might be some instabilities depending on simulation parameters, originating from where the wheels touch the road.
Kind regards,
Moritz
