Named selection of a plane of triangulated STL file for applying parameters.
This is my first time using ANSYS so this is a basic question. I am using a porous cubic material and I want to select the faces on the top surface. Since I am using an STL file my entire geometry is divided into triangulated faces. how can I select all the triangular faces on the top surface without selecting any of those in the pores? When I use box select it always selected the faces in the depressed pores too. I want to apply parameters to this selected face. Can anyone please help me?
