Results – Scenario Table
If the Full set of data is required, a scenario can be saved as an individual project. – Then Loaded into the Project Manager – Must be used to look at the results in Flomotion
The white section summarizes the solution settings and the current status of each scenario
The peach section summarizes the Output Variables. – The values will update as the scenarios solve.
The Chart dialog is learned best by trial and error so experiment with the available options.

The Tutorial Results
Are the Command Center Results Sensible?
Is this really the best Heat sink?
As new scenarios are created, one can switch between by clicking on the desired case in this list
The section to the right is a simplied version of the Drawing Board
Initialize From:
– All from Base Project
– All from No Project
– All from Previous Project

Scenario Table
For the soundcard simulation we want to use a minimum of disk space, and use the base case results as a starting point for each simulation…
Advanced Users can automate the procedure further to design the scenarios, and optimize them automatically.

Results – Chart
Charts can be created to display the Output Variables – Updates as more scenarios finish solving
These results are acceptable for our needs but refinement may be advisable if very accurate results are required..

Command Center has generated five simulations automatically.
The geometry has changed so the grid must have too.
We should check to see that the grid is acceptable for each of the scenarios! As this could be affecting the design of the heat sink.
The tutorial will start to use some of the more advanced features of Command Center to Optimize the design of a heat sink.
Command Center’s intelligence will be used to create the variations to the base case.
Hit GO!

Input Variables
Double-click the parameter that you want to vary – The ‘Use as Input Variable in Scenario’ choice will be toggled on
Check each of the cases.
Remember to check the grid for each case too by pressing ‘g’ on the keyboard.

Output Variables
For the heatsink study we will store the “Mean Solid Temperature” for component.
This gives us a measure of the case temperature of the component.
Why is this heat sink better at cooling the chip than the others?

Sensible Results ?
The results suggest that long thin fins are better than short fat ones.
Can we trust the Results? Each simulation should be treated as if we
