Aurel Systems Cadsim Plus v2.5.6
 

CADSIM Plus is chemical process simulation software that can perform mass and energy balances and simulate dynamic conditions. It is a first-principles dynamic chemical process simulator and a full-featured Computer Assisted Drawing (CAD) front-end in one package. CADSIM Plus includes a comprehensive set of generic process modules and has a number of optional module libraries for various applications.


CADSIM Plus 2.5 - What's new.

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
