Yepp, this is what i did.





Before we go further, let me clearify one thing that so far i am assuming that you are talking about cylindrical grids which has meshes:

Is mesh motion involved??
If it is there then how will you handle that in cylindrical coordinates?


PS: I have written a code for cylindrical coordinate but can not comment much on it as lots...
