I'm modelling a tall stack (37.5 m high) and the main loading on it is wind load, as shown here : http://courses.cit.cornell.edu/arch264/calculators/example2.4/02.jpg
. I want to model the acting wind pressure but my problem is that when I apply Pressure acting on Area in Ansys it applies it normal to the area of the stack and this is not right, the wind pressure acts in one direction only on the cylindrical surface of the stack as shown in attached picture.
I wanna know how to apply this type of load in Ansys 13.0 .
Thank you very much for your help.
