Master spreadsheets to generate the set of spreadsheets required as inputs to the DLB calculator.
"Each sheet defines the tags of a DLC, except the main one. The main sheet defines: wind turbine parameters, default tags values, and gusts and turbulence definitions."
"Tags are devided into 3 categories: constants (C), variables (V), and functions (F). The category is specified in the line above the tag."
Constants do not change in a DLC. Variables define the number of cases within a DLC through their combinations. Functions are tags that depends on other tags through and expression.
Parameters: Vrate Vout
