Three Hidden Secrets to Speeding up your SWMM 5, H2OMAP SWMM or InfoSWMM Model


  
Minimum Time Step               Average Time Step        Maximum Time Step

Minimum Time Step (sec)             0.984
Average Time Step (sec)              9.071
Maximum Time Step (sec)            30.000
Percent in Steady State (%)          0.000
Average Iterations per Time Step  4.821

Use a maximum time that will lower your average iterations per time step to speed up the simulation,decrease the maximum time step to lower the number of iterations, use equivalent conduit lengthening to increase the minimum time step, the model is fastest if the minimum and maximum time steps are not too small or large compared to the average time step.  Adjust the stopping tolerance and the number of iterations if you can to speed up your model You can also decrease the number of iterations or the stopping tolerance to speed up the model or improve the continuity error of themodel.   If you are doing a continuous simulation then you can have a reduced graphical output data set to speedup the simulation
  
If you have a duo or quad core computer another option to speed up the simulations is to use 1, 2, 3 or 4 cores for the simulation
