 #### Simulation
 
-Grape uses simd to calculate position and velocity. Currently it takes **~0.005** seconds to iterate 120 times over the example graph(2D). (77 vertices, 254 edges, with manybody, center, collide and link forces. Release build on a M1 Max, tested with command `swift test -c release`)

 For 3D simulation, it takes **~0.008** seconds for the same graph and same configs.
