how to manage pressure direction

amrbagh · September 2, 2011, 08:44

hi every one,

I am asking how to manage pressure direction. As i know that prssure will be applied normal to the element or area, what if i want to keep vertical direction which is parallel to gravity load. Please see the figure below.
Thank you

Not sure I follow. Pressure is a scalar quantity, and therefore has no direction

Thank you Stu

As you can see in the figure above that the pressure's direction is vertical downward.

I followed:

ANSYS Main Menu>Solution> Define Loads>Apply>Structural>Pressure>On Elements

But it gave me only normal-to-element pressure on the shell elements

I think there is a way I don't know to apply loading as shown in the figure

I beleive you are referring to the Ansys FEA solver. This forum is for Computational Fluide Dynamics, and so I don't think you will get much help from any of us sorry.

There must be a support forum for Ansys FEA somewhere else, try searching in google. Otherwise the Ansys Technical Support Team are always very helpful.
