6. Using Met Components APSIM Factorials 3 ways to add Met components
Add multiple Met components to a factor node.
Single silo component with a list of stations.
Single met component with a list of file names.

10. Advanced Factorials APSIM Factorials
Soils are not the same across all sites.
5 sites x 4 soils x 100 (5x4x4) sowing options = 2,000 runs..
Add Folders & Sub Folders, which will change the way the factorials are calculated.
It will make a list of the lowest folder nodes in the tree.

11. Advanced Factorials APSIM Factorials
Each identified folder is treated as a single set of factorials. These sets are then added together, not multiplied.
WA has 1 site x 1 soil x 100 sowing. Site & Soil are overridden Simulations
SA has 1 site x 2 soils x 100 sowing Simulations.
ALL has 3 sites and inherits all of the soils. 3 x 4 x 100 = 1200 Simulations
