New Release Version No. : 3.2.02

Date: 1-Apr-17

New release of CADSIM Plus v3.2 contains the following improvements and new features:

Drawing Mode

• Editing of multi-specifications has been improved to allow selecting of both the free and specified variables (like single specifications) after they have been placed
• Performance has been improved for repeated browsing of complex OPC connection trees. CADSIM Plus will now remember the previously opened tree and not rebuild it every time.
• Users are now required to make a valid Limiting Reactant selection before leaving the reactions wizard.
• The text entry dialog box now features improved options when entering one or more lines of text, including the selection of color, layer, angle and text
• New Ungroup Part feature allows you to remove the unique part name and un-group all of the elements in a drawing part that has been previously inserted into a drawing.
• The right-click drawing menu has been simplified and reorganized so that items are easier to find.
• A new tool allows you to open a Stream Definition (even if it is on an invisible layer) by selecting a process line and then right-clicking and selected Edit Stream Definition. Or, select Simulation > Edit Stream Definition to access a list of all process stream definitions in the drawing, and pick a process to edit. This menu item also provides a list of processes that are not yet used.
• An improved Remove Line tool (formerly called Remove Polygon Sides) has been improved to remove a selected line segment from either a selected polygon or a selected process lines while maintaining the contiguity of the remaining lines. In other words, it allows you remove a line without breaking connections (process lines) or deleting an entire polygon (requiring you to redraw it).
• A new Align Selection tool allows you to select a one or more drawing objects, select one handle, and then select a new snap location. All of the selected drawing objects would then be moved relative to the chosen location on the snap/grid. This tool can be used to help clean up imported drawings that were not drawn on a snap or grid.
• A new Change Specification Size tool that allows you to quickly resize selected specification icons by selecting preset sizes from a right-click drop-down menu list. In the special case where you may wish to hide specifications (and only show their specification lines) you can use this tool to make the icons 'tiny' or 'minuscule' (or restore them to larger sizes) by selecting their specification line.

Simulation Mode

• There are new options for customizing the format of the elapsed time display.
• A new feature allows you to temporarily hide or restore all of the currently open charts for a particular drawing, without actually closing them or minimizing them individually.
• A new manual mode has been added to AutoTune, which allows you to continue to set tuning parameters manually if the first step process identification fails. This allows you to go ahead and finish the tuning process without having to run the drawing until conditions permit AutoTune to proceed. However, you must make all of the selections manually.
• Change Order of Execution has an improved, simplified on-screen connection display, that selectively shows connecting lines for only the previous and next units, relative to the selected unit.
• The Convergence Monitor has been improved to allow an optional global setting change to all drawings in a project at runtime, eliminating the need to visit each drawing individually.
• The option to select a text color has been added to the Insert Results Record function.

Stream Chemistry

• The ability to handle bound IONs has been added. These will work with new and old style reactions. Bound IONs can be attached to follow a mass component, such as FIBER.

Unit Modules

• Efficiency calculations have been add to the Recovery Furnace and Burner units.
• A new (optional) dilution stream has been added to the following units: High Density, Tower, DStage, EOP, EStage and O2delig storage units
• New Digester unit add to the optional Fiber library
• New Cyclone unit for optional Mineral library

CADSIM Plus Version 3.0 new features:

+ Multi-document Interface:

+ A new CADSIM Plus multi-document interface allows two or more CADSIM Plus drawings to be developed as separate simulations, and then linked together to run as single simulation model. The new interface features tabbed windows, one for each drawing, that are available in both drawing and simulation modes.
+ Multi-document allows you to run each drawing to a steady-state and save a startup file, prior to running them as a group. If done properly, this can save a lot of time in getting a large simulation to run in a stable condition.
Multi-document makes it easier for individuals to collaborate on a large project.
+ A project file (filename.draproj) holds a list of drawing names and is used to launch CADSIM Plus in multi-document mode.

+ New Units:

+ Standard Library:

+ ConnectIn and ConnectOut (connection units for multi-document drawings)

+ Improved Units:

+ Standard Library:

+ Pump (added affinity laws)
+ Pipe, Pump and Valve (calculate outlet pressure when PRESSURE is not a stream variable)
+ Euler (added reset option)
+ Storage, Tower, Tank and Mixer (add Age = VariableName and plant-wide product tracking capabilities)

+ Dynamic Data Reconciliation:

+ New filter types (Integral and Savitzky Golay cubic polynomial)
+ Support for multiple filters (allows up to 5 filter types per measurement)
+ New objective functions (Gaussian, Fair, Lorentzian and Contaminated Gaussian)
+ Faster than real-time catch-up (runs DDR faster than real time)
+ Improved measurement reports in .rec file

+ Specifications:

+ Right-click to toggle between single and multiple specifications

+ Error Messages:

+ Added locate button to many error messages to help find the source of the problem

+ Runtime Factors:

+ Added runtime access to some specified factors, such as linear, ratio etc. which can now be changed on the fly without returning to drawing mode.

+ Control Lines:

+ Specification control lines can be globally set invisible. And when you click to select a specification, its control lines will appear temporarily while it is selected.

+ Reactions Editor:

+ Added estimate heat of reaction based on reacting compounds

+ Simulation Time Units:

+ Extended options for specifying the units of measure for simulated time, to include milliseconds, seconds, minutes, hours and days

Date: 01-Jun-12

New release of CADSIM Plus. Includes the following new and improved features:

Installation:

Updated Windows Installers now allow CADSIM Plus to be installed for All Users of a workstation. In addition to placing program shortcuts in all user's Start menus and on their desktops, the installer performs the following actions:

+ Places registry entries under HKEY_LOCAL_MACHINE and copies those entries to HKEY_CURRENT_USER if none are found there when CADSIM Plus is run for the first time in the current user's profile. This allows CADSIM Plus to find all of its constituent parts and settings under any user profile.
+ Places a full copy of all of the sample drawings, sample parts and user settings files (My CADSIM folder and contents) into the installing user's Personal Folder, as well as in the Common Files Folder (eg. c:\Program Files\Common Files\Aurel Systems\CADSIM Plus\My CADSIM). The first time that CADSIM Plus is run in a new user's profile, it will prompt the user to copy the contents of the My CADSIM folder to the current user's Personal Folder. This gives each user their own custom settings and copies of the sample drawings and parts.
+ A new menu item has been added (File > Copy sample drawings & parts...) which performs the My CADSIM folder copy operation on demand.
+ The optional HyProc Physical Properties Database has been moved to the Common App Data Folder (eg. c:\Documents and Settings\All Users\Application Data\Aurel Systems\CADSIM Plus\DB). This folder is set up to be shareable and writable by all users on a workstation. This prevents the database file from becoming virtualized (and duplicated) to local user's Personal Folders under Windows 7.

Charts:

+ Add user-defined titles to multi-variable charts
+ Right-click variables in runtime unit and stream information dialog boxes to quickly create a new chart or to add a new variable to an existing chart

User-created Compounds and Chemical Properties Overrides:

+ New compound editor for overriding the chemical properties of CADSIM Plus Standard and optional HyProc libraries of compounds
+ New compound editor can also be used to create user-defined chemical compounds with user-defined names

Notes:

+ The new compound editor replaces and enhances the former physical properties override mechanism that was available in v2.4 and v2.5 of CADSIM Plus.
+ The compound editor automatically generates all of the XML code required to create overrides (you no longer have to edit the XML manually) and that XML code is automatically included in the current drawing file.
+ You can also export/import overrides and new compounds into other CADSIM Plus drawing files.
+ In addition, you can now create new compounds as well as override the properties of existing compounds.

Dynamic Data Reconciliation (DDR):

+ Added new Kalman and Haar Wavelet filter types to DDR measurements
+ Improved DDR convergence performance and reliability
+ Added ability to allow over-specification of the Header unit to assist DDR convergence

New & Improved Standard Library Unit Modules:

+ Improved Tank (Chest) unit now includes chemical reactions, ability to solve local dynamic recycle loops and new height calculations for cylindrical, spherical, conical and vertical tank shapes
+ New Recycle unit provides dynamic correction of recycled mass and energy flows
+ Improved Transport Lag unit is to provide new calculated mass variables
+ Improved PID Controller to allow connection to other units via Signal streams

HyProc Library (optional):

+ New (with optional HyProc library) Winn-Underwood-Gilliland (WUG) shortcut distillation column for rapid column prototyping
+ Improved Vapour-Liquid Equilibrium (VLE) calculations

HyProc Physical Properties Database (optional):

+ Added approximately 1500 new chemical compounds to the optional HyProc database of chemical compounds

Automation / Optimization:

+ New methods and technologies implemented to enhance opportunities for process integration using CADSIM Plus runtime tools and features
+ New CADSIM Optimizer launches and controls CADSIM Plus to produce targeted optimized specification scenarios for a process model

New Example Bleach Plant Towers Model:

+ New bleach plant model located in My CADSIM\Samples\Fiber\Bleach Plant Tower Example folder (note, requires the optional Fiber Library to be installed).
