Built-in Calculated Variables – Part 3 – Advanced variables

flotools’ built-in calculated variable library includes some variables that use complex calculations beyond those that can be summarized by simple algebraic relationships. These variables are discussed in this section. Cooldown time Whenever the variable MDTHYD is available as a trend, flotools calculates cooldown time by searching the trend for the first time at which the…

Built-in Calculated Variables – Part 2 – Rate variables

In Part 1 of this article series, I discussed how some of the calculated variables in flotools are derived. The discussion focused on calculations that were derived from a single source variable. flotools performs more complex calculations that take multiple variables into account. A dedicated library for calculating rate-related variables is one such example. Before…

Built-in Calculated Variables – Part 1 – The basics

flotools has a library of calculated variables built in to the application. These variables are made available to plot automatically without any additional user input. However, the list of built-in calculated variables that are available to plot will depend on the list of variables available in the output files. We will start with a simple…
