Projected area to output parameters

Daniil85 · March 15, 2016, 17:19

Hello, all!
I trying to calculate drag coefficient of parameterized model with Fluent 16.2. For calculate Cd correctly, I need to set correct values of area, density and velocity in "Reference Values" menu, or, I need to output Force X, density, velocity and projected area from Fluent in "Output Parameters" (to calculate it outside of Fluent).

I already have output Fx, density and current velocity (through "output parameters"), but I can't find a way to output projected area.

How can I do this with Fluent scripting system? Or, is there any other way?

Have a read of this thread on calculating the area of a boundary: http://www.cfd-online.com/Forums/flu...tml#post539642

For a projected area, use the dot product with the relevant unit vector.
