Different Types of Surface Body
 

While going through an almost identical build process as my last geometry I found that when I went to meshing it gave me the error attached.



"PlugIn Error: No valid bodies found for 2D Analysis in the following parts: Surface Body"


So I went and checked what was different between this geometry and my last one that worked fine and the only difference I could see was the icon for Surface Body was now wavy instead of a box (surface body attachment).


I followed my previous steps to the letter, this time I just had more projections splitting the domain into more pieces. I can't find anything online about the differences between these two Surface Bodies and why one doesn't mesh.
