Default Symmetry Question

Hi,

I'm currently working on 3D pipe flow problems, and, in order to reduce computation time, I've modelled this as a half pipe with a plane of symmetry. When reporting values such as pressure drop, should I have to double the value which Fluent reports to get meaningful numbers?

Cheers,

Rex

Hi Rex,

You needn't do that.Just a piece of advice.Would it not be more efficient to model the case as an axisymmetric problem?

Regards, sri

Sri,

What are the differences when setting the BC to symmetry as opposed to axisymmetric?

Hi Rex,

Axisymmetric ==>2d model of a 3d problem.

where as symmetry bc can be used either in 2d or in 3d.
