z-direction flow problem
 

Hi
im having problem with the flow direction.can anyone help me with it?
im trying to make the flow goes in -z direction.i assigned the inlet and outlet regions.
is it correct if i change the direction in stationary axis in region node (0.0,0.0,-1.0) to make it goes -z direction or is it another way?
here attached the flow when im running the simulation of (0.0,0.0,1.0) for the axis in region.

did you try instead to specify velocity in your inlet region to be negative instead? did it work?

i did stagnation inlet as for the inlet,not velocity inlet.
