So it is possible for a factor node to have multiple factors by checking multiple rows in the table. Each line in the table has a checkbox, which when checked will cause the variable to be treated as a factor. If a factor node has a single child of one of these components, it will display a table of variables and their values.

There are some components that store variables within their internal structure. Selection of a component underneath the factor will enable the component to be displayed and editted as per usual. It can also handle more complex components such as a Soil component. The level is applied to a simulation by completely replacing an entire component. The default behaviour of a factor node is to treat each of itвЂ™s child nodes as a вЂњLevelвЂќ. The factor node can be configured to behave in two possible ways by replacing entire components, or by replacing individual variables within a component. Each вЂњLevelвЂќ can be as simple as a single number, or as complex as an entire Soil component, depending on how the Factor node is configured. It will do this using only a single simulation.ДЄ Factor node represents one or more вЂњFactorsвЂќ each factor containing one or more вЂњLevelвЂќ. It will then run the model with all possible combinations of those вЂњLevelsвЂќ. With the use of linking, the number of changes could be reduced, unless it is a change to the structure вЂ“ in which case the addition or removal of a component will result in changes still being necessary for every simulation.ДЇactorials attempt to solve this problem by allowing the user to define the variables to be replaced вЂ“ called вЂњFactorsвЂќ, as well as the collection of values to replace them with вЂ“ called вЂњLevelsвЂќ. If a change is required to the original simulation, it will also need to be repeated in 26 other simulations.

Assuming 3 different planting dates, 3 different fertiliser levels and 3 different Initial Water values and you would need 27 unique simulations in the tree. The difficulty encountered in this situation is that each possible combination would require itвЂ™s own simulation in the simulations tree. For the best results, it would be necessary to run all possible combinations of the three. An example of this would be to run the model with a range of Initial Water levels for a soil, a range of fertiliser rates, and a range of planting dates. When running an Apsim simulation for analysis it is often necessary to run the model multiple times whilst changing a few key variables to get results that show a wider range of possible outcomes.

Training Manual (West Africa вЂ“ English and French).The effect of residue cover on soil water storage.Cropping sequence simulations (rotations).Or maybe shell script is sufficient and i should look for specific Modelsim commands in reference manual?Д®DIT: Posting little example i've made for everyone to use. Is TCL the language i'm looking for // is it doable in TCL? If so, which commands should i make familiar with?

How to ,tell'' Modelsim (at startup) to do the commands in specified file? I'm asking because scripting isn't my area of expertise. I've already made macro files (.do) containing modelsim commands to compile & simulate desired units (+adding signals to waveform). I want it to open ModelSim, compile units, load a desired testbench, run simulation. myscript -test1 or tclsh myscript.tcl -test1 I want to make a script, which can be executed from shell like:
