CADSIM Plus v2.5

Aurel Systems is pleased to announce that CADSIM Plus v2.5, our premier chemical process simulation tool, is now available. Upgrades from previous versions of CADSIM Plus are now available for purchase. Contact Aurel for more information.

CADSIM Plus is a third-generation process modeling tool which features an advanced drawing and modeling interface. CADSIM Plus combines the power of CAD drawing with the ease-of-use of today's technical diagramming tools.

OPC and Dynamic Data Reconciliation

  • Standard CADSIM Plus package now includes these previously optional packages at no extra charge:
    • Dynamic Data Reconciliation library
    • OPC library

Automated Controller Tuning Wizard (Autotune)

  • Bump tests, and process response analysis
  • Process model identification (self regulating/integrating, direct/indirect)
  • Setting Lambda tuning parameters (user can fine tune and test proposed settings)
  • Response quickness and stability are tested on simulation before committing
  • Simulation is restored to the state that existed prior to the tuning operation to avoid simulation upset

Computer Based Manuals for Training

  • HTML pages can be integrated with 'intelligent' CADSIM Plus P&ID drawings
  • CADSIM Plus v2.5 has the ability to launch HTML content via Internet Explorer
  • Links within the HTML content can highlight predefined areas of a specially prepared drawing
  • Embedded links in a drawing can select HTML content in the browser
  • HTML content can be developed using standard HTML editing tools

New & Improved Unit Modules

  • Pass-Through unit - new (adds the ability to suspend a unit from participating in the simulation model)
  • Flash unit - improved (optional holdup and level control)
  • Uptime unit - improved (now with Weibull distributions)
  • Heat Exchangers - improved
  • Heaters / Coolers - improved
  • Dynamic Data Reconciliation - improved (allows pre-conditioning and filtering of individual measurements using Kalman)
  • Pipe unit (proportioning of viscosities of mixtures - improved)
  • Compressor unit - improved (now works within pressure flow networks, includes performance curves)
  • New Excel spreadsheets that help set up pump and compressor curves, and valve characteristics

Streams & Chemistry

  • Improved stream flashing and vapor/liquid equilibria calculations
  • Improved water/ice liquid/solid equilibria including freezing point depression

Physical Properties

  • Improved saturation temperatures
  • Improved enthalpies and entropies
  • New mineral compounds

Online Applications

  • New Startup Dynamic Profile (process snapshot file) stores and retrieves startup values including unit dynamic profiles
  • CADSIM Plus drawing can spawn an external application
  • Support for cloning a simulation from an existing online tracking reconciliation simulation to:
    • Display current data for the full process with stream details
    • Run into the future
    • Form the basis for online optimization trials
    • Form the basis for ‘what-if’ scenarios starting from current operating parameters
    • OPC client is now included in the Standard Library of process module

Graphical User Interface Improvements

  • Find Furthest Off function now displays steady-state convergence status in toolbar
  • New chart cleanup tool right-justifies and sorts open charts on your screen
  • Better window management on multiple screen workstations
  • New text tools can convert text from an object to independent text and remove extra text from an object without deleting the object
  • Ctrl + Windowing can be used to select multiple areas of a drawing

Help System

  • Updated Help system
