hi every one
how could i create a perfect structured mesh on circular cylinder (o grid).?
and what is the steps to solve it by using fluent.?
compressible flow over cylinder (density based).
and what is the range mach number for this problem?.
because at low mach number (fluent error)not convergence.and at high mach number.
thank you
