Hi,Dear colleagues,

Could you tell me how to create a curve-linear grid? further more what is the advantage of curve-linear grid compared with recti-linear grid?

Thanks

Jianxin Yuan

curve linear grid will help you a lot if your physical domain is a complex geometry. Curlinear grid will provide an easier way of defining boundary conditions. The disadvantage is the relative more complexity of the governing equations. The book: "numerical grid generation" by Joe Thompson et al., will help you better understanding the difference.

Sincerely,
