After the model has been executed, the output for the model will be displayed.
Depth vs Concentration
The Depth vs Concentration chart can be displayed by selecting the Depth vs Concentration item for the Chart Type.
Output Listing
To display the output as a text listing that will show the calculated concentrations as numbers, click on the List tab. The peak concentration occurred at 618 years, which is outside the lower and upper time limits specified. In this example the program was able to find the peak since the bounds were reasonably close to the peak time of occurrence.
