Mesher that can do 2D & 3D elements combined?

Post by drewbagel423 »

I'm trying to analyze a circuit card assembly (CCA). The biggest problem is always trying to mesh the thin copper layers along with the thicker epoxy layers between. I'm making the approximation that because the copper layers are so thin, and copper's thermal conductivity is so high, the normal-direction temperature change is negligible. Thus, they can be modeled as 2D or shell elements. I know Gmsh can handle this part, but can I (and if so, how?) also add in 3D elements for the epoxy layers and electrical components? TIA.
