Hello all,

May some one suggest references wherein some relation has been proposed ( and proved ) between grid size and cahn-number.

In my understanding, it is known that one should consider about 3 grid points ( minimum as proposed by Jacqmin) in the interface.

Well then as per that relation, Cn= int_thickness/L ( L being characteristic length of the domain).

Thus, we have Cn= 3*grid_size/L . But is this correct. I read somewhere ( can't remember where) that its best to have grid size varying from Cn-Cn/4.

May some one help in this regard.

Thanks
