How to apply pressure evenly to surface instead of on elements

Altair Forum User

Hi all, 

 

Is there any way to apply a pressure to a surface as a total magnitude across the surface? The only way I'm finding how to do it right now is by counting the mesh elements and dividing the pressure by the number of elements because the pressure card applies the magnitude to each element instead of the surface as a whole. Wondering how to apply it to the total surface because often the mesh elements are not consistent areas which applies different pressures to different elements.

 

Thanks for the responses,

No, don't divide the pressure by number of elements ! It's wrong!

If your pressure is constant, just apply it to elements.

please divide Force magnitude by surface area => to get pressure magnitude => apply this value to elems

Thank you for the responses!

I was talking about the pressure because I saw a tutorial online that divided the pressure magnitude by the number of elements on the surface, which made me think the pressure was applied like a point load onto each surface element. However, that tutorial must be misinformed.
