GateCycle plant performance monitoring software predicts design and off-design performance of combined cycle plants, fossil boiler plants, nuclear power plants, cogeneration systems, combined heat-and-power plants, advanced gas turbine cycles and many other energy systems. You can use GateCycle software for quick assessments, detailed engineering, design, retrofitting, re-powering and acceptance testing. Its component-by-component approach and advanced macro capabilities let you model virtually any type of system. »

EBSILON®Professional is a system that simulates thermodynamic cycle processes and is used for engineering, designing, and optimizing plants.

Aspen Plus is a market-leading process modeling environment for conceptual design, optimization, and performance monitoring for the chemical, polymer, specialty chemical, metals and minerals, and coal power industries. Now, Aspen Plus is even easier to use with a completely redesigned user interface, enabling customers to design new processes, deliver new products to market and optimize production faster than ever before. Aspen Plus is a core element of AspenTech’s aspenONE® Engineering applications. »

EES (pronounced 'ease') is a general equation-solving program that can numerically solve thousands of coupled non-linear algebraic and differential equations. The program can also be used to solve differential and integral equations, do optimization, provide uncertainty analyses, perform linear and non-linear regression, convert units, check unit consistency, and generate publication-quality plots. A major feature of EES is the high accuracy thermodynamic and transport property database that is provided for hundreds of substances in a manner that allows it to be used with the equation solving capability. »
