CADSIM Plus Process Simulation Software

CADSIM Plus v2.7 has been released New!
Outline

Wash Press Sample PartCADSIM Plus is an easy-to-use, fully self-contained process simulation platform which allows the user to quickly draw a process flowsheet drawing - and create a process simulation - all at the same time. It is a single tool that can both balance flowsheets and portray dynamic conditions. CADSIM Plus performs precise heat and material balances of any chemical process. It can be used for design, to find solutions for process bottlenecks, to track potential quality control problems, to refine process waste management strategies, to improve process efficiencies, and to perform on-line dynamic data reconciliation, optimization and advanced process control -- the possibilities are limited only by your imagination.

CAD Drawing Interface
The CADSIM Plus expert system has the process 'smarts' to interpret the drawing that you create, into a simulation model. Drawings look exactly as you wish them to look. We call this 'free-format' drawing. CADSIM Plus supports any level of drawing complexity - from a simple block diagram to detailed engineering drawings. The CAD capabilities of CADSIM Plus are especially suitable for detailed P&ID, P&C or logic type drawings. CADSIM Plus Drawings can also be exported to AutoCAD® and other standard CAD programs.
Runtime Interface
CADSIM Plus has an 'electronic flowsheet' runtime simulation mode interface. The original CADSIM drawing becomes an interactive and animated simulation tool. The CADSIM Plus Living Drawings™ allow the user to change conditions while the simulated process is running. Simulation results (numbers and text) can be formatted in any way at any location on the drawing. Results are automatically updated with each simulation iteration. Strip charts are used to log dynamic responses. A single click on any drawing object gives access to runtime functions such as the ability to change runtime controller settings and set-points. Any graphical object can be animated. Some uses of animation include; to show tank levels, pump on/off conditions, valves open/closed, changing colors to show species or temperature change, etc.
Suitability to Task

The CADSIM Plus simulator is of special interest to process engineers for tasks such as process troubleshooting, prediction of future process conditions, and searching for solutions to dynamic control or process stability problems in the plant. Some examples of dynamic simulation use in process design and operation include:

  • CADSIM Plus - Object InspectorProcess investigation and optimization:
    • process operation for optimized quality and operating costs
    • prediction of future operation; product and environmental quality
    • water management, use reduction and contamination control
    • transient condition studies
    • 'what if' studies
    • storage requirements to allow shut-down and start-up
    • containment build-up dynamics and inter-area cross links
    • energy studies
  • Process operation scheduling
  • DCS checkout and test bed
  • Operator training
  • Process control, loop tuning, and interaction with the entire process
  • Process control strategy development and model building
  • On-line dynamic data reconciliation applications
  • On-line optimization and advanced process control applications

 

Design Capabilities
Units, such as high density storage tanks, allow furnish changes to be tracked; process streams can track fiber fractions and special components such as metal ions, money, viscosity, freeness, brightness and kappa; pressure flow networks and friction losses can be used in pressure related design and control problems; a variety of controllers and PLC logic units allow simulating special control events, etc.
Return on Investment
One client claims savings of several million dollars per year in a single mill after a few days of process investigation with CADSIM Plus. Several consultants claim that they can draw a drawing faster with CADSIM Plus's flowsheet drawing capabilities than they can with the more general purpose CAD software packages, and at the same time they have configured a simulation, without the need of creating more than one document.
Process Modules

The CADSIM Plus drawing is interpreted using dynamically loaded libraries of simulation building blocks (equipment, controllers, logic, streams etc.). CADSIM Plus uses the SmartLink expert system to select and load the appropriate modules from the available libraries at runtime. With this mechanism, CADSIM Plus can host different types of simulation 'personalities'.

The basic CADSIM Plus package includes a complete Standard Library of controllers, process equipment, logic and calculation building blocks. There are also several Optional Libraries of modules available.

Academic Software Program
Aurel Systems has a program for donating software to Universities and Schools for non-commercial, academic uses. In addition, we arrange licensing for a university's commercial uses at an additional cost. We feel that it is very important to give students access to leading edge technologies. If you have an appropriate program that would benefit from access to chemical process simulation software, please contact Aurel to discuss the details.
Pricing

CADSIM Plus is one of the best values available in the simulation software marketplace. It is the price leader, but don't let that fool you. CADSIM Plus is packed with features that you simply will not find in any other commercially available chemical process simulator. It is available in full and runtime versions. And Aurel includes the first year of software maintenance and support at no extra charge when a new license is purchased.

CADSIM Plus is offered at discounted rates for multiple licenses purchased (in a single purchase, or over time), and it is also available for short or long term lease. CADSIM Plus can be licensed on a per-workstation basis, or via a flexible multi-user, network-based license. Contact Aurel for more information.
