While newer iterations of Aspen HYSYS (such as Aspen Plus/HYSYS V11, V12, and V14) dominate current corporate environments, version 8.8 remains active globally. Many engineering firms, public utilities, and educational institutions continue to use version 8.8 due to its stability, lower hardware requirements, and the long lifecycle of capital project files originally designed in the V8 ecosystem. Its core calculation engines are identical to those found in newer versions, making skills learned in HYSYS 8.8 directly transferable to modern cloud-based engineering platforms.
To build a simulation in Aspen HYSYS 8.8, engineers follow a structured hierarchy that isolates physical property definition from flowsheet convergence. Step 1: Component List Definition
Powered by the Aspen Economic Evaluation engine, this tool updates capital costs (CAPEX) and operating costs (OPEX) continuously as the user modifies equipment sizes or process configurations. Enhanced Sulsim Sulfur Recovery
One of the most notable features of version 8.8 is the integration of safety analysis directly into the design workflow. Users can size, select, and verify pressure relief valves (PRVs) and rupture disks according to API 520 and 521 standards.

The FLR project has been developing and providing fishery scientists with a powerful and flexible platform for quantitative fisheries science based on the R statistical language. The guiding principles of FLR are openness, through community involvement and the open source ethos, flexibility, through a design that does not constraint the user to a given paradigm, and extendibility, by the provision of tools that are ready to be personalized and adapted. The main aim is to generalize the use of good quality, open source, flexible software in all areas of quantitative fisheries research and management advice.
Development code for FLR packages is available both on Github and on R-Universe. Bugs can be reported on Github as well as suggestions for further development.
