How to apply wind pressure by pload,pload4 or another?

young

hi,

    I have a problem that I need to simulate the wind blowing on an inclined plane. Theoretically, the wind force is equal to the wind pressure multiplied * the projected area. But when I use pload4 simulation, the wind force is the wind pressure * surface area; When using pload simulation, the wind force is the wind pressure* surface area, and the direction is perpendicular to the object surface.

  As shown below。may be there are some ways to simulate this state，expecting  an answer .Thank you .

Hi Young,

You can generally use PLOAD4 for this kind of case if you want to apply pressure that's not normal to the element surface as I think is the case here for wind loading in your model.  A PLOAD4 gives you the flexibility to define pressures with a vector direction, other than normal to the elements. A PLOAD doesn't have this option and the pressure direction is set normal to the element surface based on the grid points.

Thanks,
