add pressure to the edge of the 2d surface

Altair Forum User

i have a 2D airfoil, but i want to add pressure to the edge of the airfoil, do you have any idea how to add pressure normal to the curved edges?

Hi 

 

Pressure loads are always applied normal to surface irrespective of the feature. you can either select the element along the curved surface or if you are using 3D element then select the face and apply.

this is for a 2D surface only structure, i knew how to add pressure to a surface in 3D case.

but for 2D case, the pressure can be only applied to the edge line.....

can you help me again?

Hi dajeet

 

You can apply pressure on an edge line as well. Change the selection to free edges and select the edge line.
