Hi folks,

I am performing a FEA analysis and creating a shell in Workbench (Surface from Faces). I assigned a 2mm thickness to my desired material to resist a certain pressure. I want to refine the mesh to something that looks like the yellow picture (mine is in pink), but ANSYS cannot refine the elements in the thickness. Do you have any other suggestions for successfully running this analysis?

Alternatively, is there another way to create this wall from my solid geometry that is not a shell? I am using Extrude but not sure what should be my "Direction Vector" because i want the thickness to be assigned perpendicular to the 188 faces of my geometry but not sure what to choose so that ANSYS will assign the thickness perpendicular to each face

Hello Farah, 

looks like the second pictured mesh (yellow) used inflation layers from the inside boundary. You can tell by the fact that the inside edge has prismatic cells but the outside should triangles. That could be an option for you.
