  4. Viability (age) check New Landuse Units A new landuse unit generated Entire system check & update Regional control & policy check Neighbor condition check Transportation condition check Transp. check at new site Neighbor check at new site Site selection for new growth A Flowchart of DUEM Simulation Procedures a new round simulation Initial Landuse Units Not successful simulations dead inactive Active seeds A successful simulation Invalidating new growth Accepting new growth Generating new growth Land use type for new growth

  5. Turn on constraint Factor Create environment Load constraint grid Setup age property Load initial landuse file (grid) Load simulation rules Load active seeds (landuse units) A Flowchart of DUEM Software Running Procedures

  6. Turn on constraint Factor Create environment Load constraint grid
