By using its stream-based architecture, CADSIM Plus's FlexSpec™ technology allows you a high degree of flexibility in specifying your process simulation problem. You can equate one value to another, ratio, or calculate values for any unit module, or stream parameter. If you need even more complexity, you can use a series of equations, or cascading equations. Values can be filtered, transformed, or passed through PID, or Fuzzy Logic controllers. Different values can even be selected for differing process conditions. CADSIM Plus specifications appear graphically on your flowsheet model, so that you can survey and adjust these relationships quickly and easily. There are no values hidden inside blocks.

Living Drawings™ technology allows you to create a simulation model by sketching a process flowsheet. Anything that you can draw can be interpreted into a simulation by CADSIM Plus.

An Open Simulation Systems Architecture™ (OSSA™) was developed by Aurel to make CADSIM Plus an open simulation interface platform. CADSIM Plus can host different simulator "personalities". It is extensible. Any user can include their own custom process modules. In addition, source code is available for all process modules.

CADSIM Plus's SmartCalc™ accelerates both simulation calculation and results display. SmartCalc manages flowsheet calculations to speed up runtime performance. SmartCalc-enhanced calculation times can be an order-of-magnitude faster than what is possible with any other process simulator.

CADSIM Plus uses a hierarchy of process objects and a rules-based selection process to choose the most appropriate modules for any given simulation at runtime. SmartLink™ allows CADSIM Plus to host many differing simulation 'personalities'.

CADSIM Plus SmartParts™ automatically align themselves with the orientation of a pipe line, and may be set up to remove line segments, when they insert themselves into a line. SmartPart text automatically reorients itself relative to the bottom of the drawing, in order to maintain drawing readability.

Information re-scoping, promotion, and hiding allow the user to choose the level of fidelity needed for any area of the simulation model. This offers maximum model flexibility with a minimum amount of modeling time spent.

User-defined Quality or 'Special' Parameters allow tracking of components, which do not participate in normal mass, energy, and momentum balances, such as dollars, pH, viscosity, strength, and H+.

CADSIM Plus is fully compatible with your CADSIM and CADSIM with Coach drawing files, making it easy for you to adapt your older steady-state process simulation models to the new CADSIM Plus dynamic process simulator.

In addition, drawings with simulation results can be plotted directly from CADSIM Plus or exported to printers, plotters, AutoCAD, Intergraph, and HPGL (plotter language) devices.

A separate utility allows you to annotate and merge CADSIM Plus simulation results into your AutoCAD drawings. Also, AutoCAD drawings can be imported as drawing templates by CADSIM Plus.

CADSIM Plus supports the following communication protocols and standards:

• DDE (Dynamic Data Change) - Can link to other Windows programs running on your PC. CADSIM Plus can act as both a DDE server and client.
• COM (Common Object Model) - Can link to other Windows programs running on your PC. CADSIM Plus can act as both a COM server and client. Provides the ability to control CADSIM Plus simulation mode from another program, such as Excel.
• OCX (ActiveX) - Permits Macromedia Authorware to link and run CADSIM Plus via the COM interface.
• OPC (OLE for Process Control - This optional library allows OPC connectivity to process control devices and software on your Local Area Network (LAN)
• SimcaQP module (Umetrics) - Provides access to Umetrics Simca-P multi-variable prediction software (Simca-P and SimcaQP are available for purchase separately from Umetrics).

CADSIM Plus runs well on virtually any personal computer with 32 bit Microsoft Windows® installed, including Windows 2000, XP, Vista etc. Faster processors provide better runtime performance. We like to say, 'if it will run Microsoft Office, it will run CADSIM Plus!'

A 19 inch CRT (or larger) or a 19 inch LCD SXGA or UXGA monitor are recommended for CAD drawing, and to give you a larger view of your model at runtime. 21 inch (or larger) LCD monitors are becoming reasonably priced and offer extremely sharp imaging capabilities that easily exceeds their CRT equivalents of similar size. Laptop computers with a 15.4 inch (or larger) SXGA or UXGA (or better) screen are ideal for working with CADSIM Plus away from the office.
