Metaparameter Explorer

The Metaparameter Explorer allows you to calibrate a variable using an expression. For example, if you want to calibrate a link variable, you can specify this in the Metaparameter Explorer, and then assign it a value using the Function manager.

To open the Metaparameter Explorer, right click on the required function and choose Add Usage.

Suppose you want to calibrate the storage routing exponent (m) on one of the reaches in a Source model. Initially, identify which link or node in the model you want to place the expression in. Then, use the Metaparameter Explorer to allocate a parameter to the variable (steps outlined in Figure 1).
