simpleFoam abort code 1

Have been trying to get trees to work and having a tough time. The trees are mesh volumes that are big to encompass canopy of multiple trees.

I can get it all to run with terrain + buildings, but if I add all my trees then simpleFoam does not run at all. I had the idea that the problem is that the buildings and the tree volumes intersected, so I went around and boolean differenced all the tree volumes to no avail.

I tried processing all the tree volumes as individual trees as well as doing it as one disjoint mesh.
