Change Front and back????
 
Hi dear foamers.

I have a problem,please help me to solve it. :)

I transfer my 2D geometry from gambit to OpenFoam Successfully.

but i have this question that:
I know that if in B.C front and back is empty my solve is 2D!!!but I want to have 6m depth in direction Z????
Can i change B.C front and back for this reason???
How to do this work???

Thanks for your attention.

when it is 2D, so why do you want to give special depth to it?
However you can change aspect ration or scale of your import geometry with:

Code:

transportPoint -scale '(0.001 0.1 1)'

Thanks for your answer.
 
transportPoint -scale '(0.001 0.1 1)'???
where do add this line???

I ploted 2D geometry in gambit: 6m*1cm ) ,but really my Dimensions Geometry is :1m*6m*1cm.

Now i want to my run has 1m for depth it.
for me it is easier that used 2D run Instead 3D model!!!!


please tell me, how can i do this???
Thanks for your attentions.

after importing your mesh, you can scale it with above command in terminal!
of course you should choose appropriate scale for your geometry
