how to defined the direction vector
 

Hi..... I choice porous media that it simulate fluid flow in the channel . otherwise . How to adjust the argument i **direction-1 vector**,**direction-2 vector** in the channel panel. FOR EXAMPLE Now, i simulate three dimensional model , before the operation , i define direction-1 vector {1,0,0} again direction-2 vector {0,1,0} Is it a wrong or right ?????

thanks in advance

Pl. read section 6.19.4 of FLUENT User's guide vol 1. You can make use of "Line tool" for 2D & "Plane tool" for 3D flow. Best Luck.
