CADSIM Plus v3.2 New!

Aurel Systems is pleased to announce that CADSIM Plus v3.2, 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.

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 continuity 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 specification resize 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 added to the optional Fiber library.
  • New Cyclone unit for optional Mineral library.
