 ### Computational Benefits
 
-- Reduces computational domain size by a factor of 2 for each symmetry plane
+- Reduces computational domain size by a factor of 2 (note: only one symmetry plane is supported)
 - Can significantly decrease mesh size and computation time
 - Allows allocation of computational resources to higher mesh resolution in the simulated portion
