Back again with another annoying problem. I’ve been attempting to mesh a large complex urban environment and it has been relatively problem free with the exception of this problem. The project link is here. The mesh basically creates strange deformations as if it is overlaying each other causing the cells to be very skewed and when a simulation is attempted, instability will occur resulting eventually in an error. Below are examples of where these occur, but they do occur everywhere within the geometry.

Normally if I were out of ideas I would re-mesh it while tuning the refinements to get it right but if you look into the project itself it is very costly to always re-mesh such a geometry, hence any help would be much appreciated!
