Setting analysis parameters
Parametric study analysis management is smililar to statistical analysis. We focus on setting up parameters for parametric study only. First step is to select functions which parametric study is to be performed. Next step is to determine active variable. On rightlist click the variable which is is active. Pasive variables means that the variables will be treated as constant. User can prescribe constant value in second column.

At the bottom of windows type of design of experiments can be choosen:
Variable selection
Determination of set of discrete design variables is curcial for parametric study problem statement. Often fast reduction of design variables set is needed. Excluded variable is replaced by constant. Doe exclude variable form analysis click on "variables" tree subitem. Desribed below dialog box will apear:

if particular variable is selected it will be used in the analysis. If not constant value will be used taken from secong column.Note that: Set of dependent random variables is setermined automatically by selecting limit state function. This window will be empty if no function is selected. So user can eliminate a variable only. To add a variable, definition of limit state function have to be enriched. Variable selection is applicable to all reliability methods.
Results of parametric study
Parametric study just computes selected functions for all values of choosen discrete design variable catalog. Table of result values has a form:

Variable "A" in first column has values taken from catalog. Choosen function "cn" is tabulated in last column.
