Hi!

I have a preprocessed model of solid elements. I don't have a geometry to reference from or more specifically, a face that I can generate a surface set from. My question is with this context. I want to apply a pressure on the top of my model. Unfortunately, I have no scripted method of selecting the surface elements. Using macros does not work because I am trying to automate multiple models that vary. However, I do have solid elements set and node sets. From my understanding, I have to find the faces of my elements. To me at least, it's clear where the elements are facing externally. How would I be able to select the faces of solid elements through script and turn them into a surface set so I can apply a pressure?

Second, I tried a workaround. I generated a 2d mesh on top of my 3d mesh. But my issue is that I don't want the 2d elements to have any properties. I am simply using it to select the faces of my 3d mesh. Unfortunately, I think I misunderstood the program and I have to apply a property to it. Is there no way to transfer property of the face of the solid mesh it is associated with to the 2d mesh? Or is there no way to bypass having no property for this 2d mesh?
