more details on moving boudaries

Hi, I need a help in how to implement a moving boundary conditions on the wall (fixed velocity on the wall). how to update this value in time.

thanks

If your wall is viscous then set all velocity components equal to the velocity components of the wall. If the wall is inviscid then set the normal component of the fluid velocity to the normal velocity of the wall and extrapolate the tangential component of the fluid velocity from the fluid nodes adjacent to the wall.
