Hi guys, 

I'm working on simulating a large assembly. The assembly has a mix of solids and shells.

As you can see in the pictures I shared, the shell parts extend to the mid point of the solid piece.

I used split lines on all parts to allow compatible mesh. 

I'm seeing inconsistency with the overlap; the top flat piece seems perfectly meshed but the curved piece seems to be having trouble.

My question is, will this produce accurate results?

For clarity, this is what the shells look like without the solid piece
