tamsilian is an unknown quantity at this point
I was trying to do the cylinder tutorial explained in the programmer's guide.
Once i've finished to do it I've started to wonder how to make boundary value for cylinder.
What boundary condition I've to give to the cylinder instead of symmetry? It should be Wall? and if is this the right way how i can specify the angular speed of the cylinder? I've to specify a non uniform speed (point to point in cartesian coordinates) for all the points of the cylinder's surface?if anyone coded the same program please sent me.
thanks in advance for the help
