On Coordinate system used in Fluent

varghese

Hallo! Friends,

I would like to know which coordinate system is used in Fluent in defining the governing equations! Is it Cartesian,cylindrical or spherical, or all of them? If there are different coordinate systems available, how to choose one of them?

This became important in one of my calculations, where I wanted to use a 2D reduced problem definition for flow in a 3D cylinder. I reduced the 3D geometry into a rectangular surface. But a rectangular surface is a 2D reduced form, of both a cylinder and a right parallelepiped. Only if I can implement the governing equations defined in cylindrical coordinate system, for the cylinder case, can I distinguish between them. Or does there exist some other way?

Hope the problem is clear enough!

Thanks in advance, for any useful suggestion!
