1.-Open the file Oil_Water_Separation_System.m in Dymola 2.-Simulate the model that we want separately: BLOCK_DEWATERER->Simulation_Dewaterer BLOCK_DEOILER->Simulation_Deoiler BLOCK_GRAVITY_SEPARATOR->GravitySeparator 3.-the parameters can be modified in the simulation environment except the swirl numbers in Swirl separators it should be modified entering in the BLOCK and in the model of the block change "s" for strong "w" for weak or "l" for large.
