PLS LET ME KNOW I SHOULD APPLY GRAVITY VALUE OF 9.81 ALONG WHICH DIRECTION Y OR Z? INITIALLY I THOUGHT GRAVITY IS ALWAYS ALONG Y OF COURSE FOR A GLOBAL COORDINATES BUT I SAW SEVERAL CASES WHERE IT WAS CHOSEN Z
I WANT TO DO FLOW OF WIND AROUND A STATIC STRUCTURE SAY BUILDING ,A TREE ,AN OBJECT WHAT TO CHOOSE GRAVITY DIRECTION -Y OR -Z?

It would depend on the global position of your model and its orientation. That is why there is no real fixed direction. If in your case the building is raising in the Y direction than you apply gravity in the Y (negative value) direction. For the case of building or tree see in which direction the normal vector of the ground is pointing too and apply accordingly the gravity (in this normal direction).
