I recently updated my OpenFOAM version 4.0 to 6. I'm facing an issue in the direction of flow. My flow is always pointing in x direction. Hence I tried to change the flow axis in a tutorial windaroundbuildings in simplefoam. The default wind direction was 'x' axis, so there was no issues. When I changed the Uinlet to (0 10 0) I mean the flow is in y direction, still the flow is pointing in x direction. I'm concerned about this flow direction because in my real case, I need the flow to be in 'y' axis but the flow is along 'x' axis.  Is this a bug in openfoam 6? (I have attached the image of the tutorials in which I changed the flow axis to be 'y' but still in paraview glyph is along 'x' axis)

Also I tried to run an interfoam solver, initially I set the writeinterval to be 0.5 then I thought of reducing it to 0.1, when the time was around 0.2 seconds to see what happens at 0.3 seconds, instead the program terminated with error 0.1 has already completed. Is it also bug where we can't adjust or reduce the writeinterval in OpenFOAM 6?
