flotools 1.4 represents a major improvement in plot viewing and editing that addresses a number of pain points and feedback items we’ve received over the past few months. We’ve carefully redesigned the experience to make it easier than ever for flow assurance engineers to create and export report-ready plots. This post describes the following significant…

One of the more recent additions to flotools is a feature we call Imported Data. Imported Data allows you to add a series to a plot using data that is not in the OLGA files themselves. The example below walks you through the steps required to add a phase envelope to an X-Y plot. 1. In a workspace, open the Imported…

flotools can be installed using one of two different installation files. 1. flotools_setup.exe This installer is intended for attended, end-user installation and provides a user-interface for specifying installation options and launching flotools when the installation has completed. It also installs the .NET Framework 4.5 if it is not already present, then installs flotools. Command-line options…

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…

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…

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…
