You shoo ld use this section to find those conduits that ate slowing your motlel down. Use motlify conduits to alter the length of Che slow conduits to make your simulation faster, ox change the conduit name to "CFP9E?????" where 7?1?? are any characters, this will lengthen the conduit based on the ma tlel time step, not the value listetl in modify conduits.
