Setting analysis parameters
Metamodel analysis management is smililar to statistical analysis. We focus on setting up parameters for metamodel only.

Next step is to determine active variable. On rightlist click the variable which is is active and prescribe the range of variation. Pasive variable means that the variable will be treated as constant. User can prescrobe constant value in fourth column.

At the bottom of windows type of design of experiments can be choosen:
- LH,
- OLH,
- Full factorial,
- CCD,
- Custom design of experiments taken from file.
Function selection
When "Add function" function selection and metamodel types choice dialog is displayed:

User is able to select a function from list an assign choosen metamodel types to be computed for selected function.
Results
Analitical expressions are obtained as the results of metamodel analysis. Example results are displayed below:

To open this dialog box click on the "Metamodels" tree subitem of "Results" item. User can select a metamodel and add it to functions set by pressing "Add to function". This function can be uset in all other analysis.
