I have a steel pole, 10'' diameter and it is fixed at the base. I want to apply a pressure on a portion (let say half of the section). Is it possible, how ?
Welcome to the forum! You can do this probably most easily by using a split line to break the surface up. The part remains continuous, but you can specify where loads are applied.
I'm not sure to understand how to do it. Is there a tutorial ?
Not that I'm aware of, but you can check the Help for 'Split Lines'. You would do this in the modeling window, and the general idea (in this case) is to use a 2D sketch projected onto a body to split the surface up. You would only need to make a sketch on a plane parallel to the pipe axis, and draw a line perpendicular to the pipe axis but extending beyond the pipe in both directions, at the location you want to seperate the pressure load.
In your simulation, you choose only the part of the surface you want to apply pressure/force, and reference direction if necessary.
I hope I'm not misunderstanding what you're trying to do and that this helps
