COCO (CAPE-OPEN to CAPE-OPEN) is a free-of-charge CAPE-OPEN compliant steady-state simulation environment consisting of the following components:

DWSIM is an open-source CAPE-OPEN compliant chemical process simulator for Windows and Linux. Built on the top of the Microsoft .NET 4.0 and Mono Platforms and featuring a rich Graphical User Interface, DWSIM allows chemical engineering students and chemical engineers to better understand the behavior of their chemical systems by using rigorous thermodynamic and unit operations' models with no cost at all. Since DWSIM is open source, they can see how the calculations are actually being done by inspecting the code behind during execution using free tools available elsewhere. »

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. »

CHEMCAD is Chemstations’ intuitive suite of chemical process simulation software that broadens an engineer’s capabilities and increases productivity. CHEMCAD supercharges an engineer’s efficiency when facing the toughest chemical process models or addressing day-to-day challenges.

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

Program that solves numerically algebraic systems of non-linear, and linear, equations where one only has to write down the equations to obtain the results. It also includes a database of thermodynamical properties for many substances and a symbolic mathematical program to perform mathematical operations. Basically the program is an open source clone of the EES but written in Java.

PRO/II® process simulation software is a steady-state simulator enabling improved process design and operational analysis. It is designed to perform rigorous heat and material balance calculations for a wide range of chemical processes.

VMGSim is used around the world to model existing processes and to design new facilities from the ground up.

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. »

TRNSYS is a transient systems simulation program with a modular structure. It recognizes a system description language in which the user specifies the components that constitute the system and the manner in which they are connected. The TRNSYS library includes many of the components commonly found in thermal and electrical energy systems, as well as component routines to handle input of weather data or other time-dependent forcing functions and output of simulation results. The modular nature of TRNSYS gives the program tremendous flexibility, and facilitates the addition to the program of mathematical models not included in the standard TRNSYS library. TRNSYS is well suited to detailed analyses of any system whose behaviour is dependent on the passage of time. TRNSYS has become reference software for researchers and engineers around the world. Main applications include: solar systems (solar thermal and photovoltaic systems), low energy buildings and HVAC systems, renewable energy systems, cogeneration, fuel cells. »
