SimulationX is a graphically-interactive tool for the holistic modeling, simulation and analysis of multi-domain systems from 1D to 3D. Multi-level customizing options and SimulationX’s capability to adjust the model’s complexity by mouse-click allow modeling in every step of the design process. Ready-to-use model libraries, e.g., for mechanics, multi-body systems, power transmission, hydraulics, pneumatics, thermodynamics, and electric drives are written in Modelica language. Libraries are extendable by Modelica-based modeling using the SimulationX TypeDesigner. A comprehensive API supports the integration into any CAE, CFD, CAD or database tool environment. Versatile interfaces offer plenty of opportunities for exporting models in terms of Simulink S-function and C-Code for HiL, RCP and other real-time applications. Different features (tracing, performance analyzer, switchable model complexity) support users in achieving real-time-capabilities.

EES ('ease') is a revolutionary program which will change the way you think and work. EES provides capabilities not found in any other equation solving program. EES will solve large sets of non-linear algebraic and differential equations. EES also provides publication-quality plots, linear and non-linear regression, optimization, unit conversion and consistency checking, and uncertainty analyses. Built-in functions are provided for thermodynamic and transport properties of many substances, including steam, air, refrigerants, cryogenic fluids, JANAF table gases, hydrocarbons and psychrometrics. Additional property data can be added. EES also allows user-written functions, procedures, modules, and tabular data. EES can also interface with REFPROP and other NIST fluid property programs. REFPROP provides the most advanced methods for estimating the properties of mixtures. The Professional version allows many other additional features including animation and the ability to make stand-alone programs.

gPROMS is an equation-oriented modelling system used for building, validating and executing first-principles models within a flowsheeting framework. Models are constructed in the gPROMS ModelBuilder by writing down the fundamental chemistry, physics, chemical engineering, operating procedures and other relationships that govern the process or product behaviour. The resulting model is then validated against observed data — typically, laboratory, pilot plant or operating data — to adjust model parameters such as heat transfer coefficients to match reality as closely as possible. Of course, you don't need to create a model from scratch every time – you can use one of the many state-of-the-art gPROMS model libraries, or create your own library for publishing throughout your organisation. Solution accuracy – for multiple applications The first-principles approach combined with rigorous validation results in models of unprecedented accuracy. Once a model exists, it can be solved in many different ways to perform many different activities – for example, steady-state simulation, dynamic simulation, parameter estimation, model-based experiment design, steady-state and dynamic optimisation, including integer optimisation, or generation of linearised models for use in control and online optimisation, across the process lifecycle. This means that once you have invested in creating an accurate gPROMS model of your process you can use that model wherever it can generate value, to ensure multiple return on investment. PSE ModelCare PSE recognises that creating high-accuracy process models requires expertise in many different domains – chemical engineering, physics, chemistry, hydrodynamics and modelling and numerical solution itself. That is why we provide the ModelCare service. ModelCare aims to help companies deliver fit-for purpose modelling applications rapidly, while transferring modelling know-how to customer organisations.

R is a language and environment for statistical computing and graphics. It is a GNU project which is similar to the S language and environment which was developed at Bell Laboratories (formerly AT&T, now Lucent Technologies) by John Chambers and colleagues. R can be considered as a different implementation of S. There are some important differences, but much code written for S runs unaltered under R. R provides a wide variety of statistical (linear and nonlinear modelling, classical statistical tests, time-series analysis, classification, clustering, ...) and graphical techniques, and is highly extensible. The S language is often the vehicle of choice for research in statistical methodology, and R provides an Open Source route to participation in that activity. One of R's strengths is the ease with which well-designed publication-quality plots can be produced, including mathematical symbols and formulae where needed. Great care has been taken over the defaults for the minor design choices in graphics, but the user retains full control. R is available as Free Software under the terms of the Free Software Foundation's GNU General Public License in source code form. It compiles and runs on a wide variety of UNIX platforms and similar systems (including FreeBSD and Linux), Windows and MacOS.

The aim of this project is to set up a tool composed of * a graphical Modelica editor, aimed at writing the plant model; * an editor for IEC 61131-3 languages (currently, the Ladder Diagram, Sequential Functional Chart and the Functional Block Diagram are being considered), aimed at writing the controller model; * a compiler to turn IEC 61131-3 code into executable code on selected target platforms; * a pre-compiler capable of translating both the plant and controller model in a single Modelica file, to be fed to any Modelica translator for simulation; * an interface to the OpenModelica compiler, for Modelica code parsing, compilation, and simulation; * a simulation output browser. SimForge is fully written in Java (thus crossplatform), uses the XML language as internal data format for maximum openness and transparency, and is entirely free software, released under the terms of the GPL license. It is the authors' intention to allow SimForge to operate with any Modelica compiler, so as to maximise its use and to have the maximum amount of feedback for improvement. Currently, SimForge works with the open source OpenModelica compiler. If you are not interested in IEC 61131-3 controller development, you can still use SimForge as a full-fledged, free, open-source graphical user interface to the OpenModelica compiler.

Conceived by the Hydraulic Institute (HI), Pump Systems MatterTM(PSM) is an educational initiative created to assist North American pump system users gain a more competitive business advantage through strategic, broad-based energy management and pump system performance optimization. A primary objective of the initiative is to change the decision-making process for the purchase of pumping systems. Pump Systems Matter will promote educated decision-making based on life cycle costs and systems optimization concepts, thereby accounting for energy, maintenance and other significant costs factors of operating a pumping system. PSM seeks to transform the market by changing owner and operator decision-making on pumping systems from a focus on first cost to a focus on life cycle costs, while helping pump users capture significant energy-savings and performance improvements. Pump Systems Matter, to be successful, requires collaboration and teamwork between pump manufacturers, pump supplier OEM's, pump systems designers, contractors and users, as well as utilities, the energy efficiency program community, government agencies, academia and other associations. Alone, this challenge is too big for any single group. Working together, PSM Sponsors can identify the key market opportunities, technology, training, tools, education and incentive programs that will transform this market, reduce energy consumption, reduce greenhouse gas emissions and place a focus on buying based on life cycle cost and total cost of ownership. PSM will collaborate with its stakeholders to build PSM into a significant new educational program offering unique resources of value to all participants. The PSM organization invites interested organizations to become sponsors. To learn more about how Pump Systems Matter was inspired and developed, review "Why Pump Systems Matter," a paper presented at the ACEEE Summer Study on Energy and Industry on July 20, 2005.
