New Models and Add-Ons Model Improvements Model and Species Improvements

New TCE Add-Ons

The following new Add-ons all relate to flexible integration in SysCAD plant models of third-party thermodynamic calculation engine (TCE) software performing detailed equilibrium and thermodynamic property calculations.

Previously in BETA release, they have been significantly improved in Build 139.

The direct integration of these specialist software programs in SysCAD provide a significant range of new and detailed applications in the SysCAD flowsheet simulator for a range of pyromet, hydromet and aqueous chemistry systems:

Improved Models for each TCE add-on

  • Model Configuration
  • Direct Calc
  • Side Calc
  • Reactor

New TCE Models


New Unit Models

Dynamic Unit Model Improvements

  • Precipitator3 Dynamic Mode - added tank level control; improved bypass options; and the internal calculation iterations may be decoupled from the project time step using Safety.TimeStep.
  • Thickener2 model - New overflow control options.
  • Conveyor Belt improvements (these enhancements are also applied to the latest version of Build138)
  • Multi-Storage model- New option to display and report the combined total of all stores in a Multi-Storage model. Includes options to override the temperature.
  • Dynamic Tank displays IOs in order of descending height, also in most recent version of Build138.
  • Slew Rate Controller: user can set the "Output" value when stopped. Output Minimum and Maximum now correctly limits the "output" value.

Species Properties Improvements

User Interface Improvements Other Improvements Project Upgrade | Changes that Affect Results

General Improvements

  • Importing Species from HSC Database - Added new import functionality for HSC8 and newer. To use the new import functionality, the HSC COM interface is required. This requires user to have a licensed working copy of HSC installed.

Graphics Improvements

  • Graphics Copy and Paste between projects: when pasting the copied graphics into another project, any reference files used by the copied models (e.g.: reaction, pgm, mp, csv files) will be copied to the new project location.
  • Graphic Symbols Library - New Symbols subfolder for Shapes. This contains some basic drawing shapes such as circles, squares and triangles. See BaseFiles\SysCADSymbolsList.pdf
  • Animation - Added option "Send to Annotation" to the Access Window - context menu, this works during Insert Annotation step, engineering units provided will be used correctly.

"Under the Hood" Changes

Tutorial & Examples

  • Updated Tutorial documentation. Please see Tutorial in the Help documentation.
  • Example Projects distributed with SysCAD have been updated
  • New Example projects: (e.g.: PHREEQC and ChemApp Examples)

Discontinued Unit Models and Functionality

Project Upgrade

  • Solvent Extraction Unit - Projects using isotherm: user must change the old Isotherm method to Isotherm2 in Build138 before upgrading to Build139.
  • Precipitator3 - Projects with Precipitator3, user must finish the upgrade process in Build138 first (instructions here), before upgrading to Build139.
  • Users with existing projects using TCE add-on models (AQSol, ChemApp or PHREEQC) need to manually update the configuration file to contain the TCE database location. Click here for details.
  • The old Screen & Cyclone models have been discontinued since Build137 and will no longer work in Build139. Projects with these old unit models must be changed to Screen 2 and Hydrocyclone models before upgrading to Build139.
  • PGM Variable Name - Maximum length of PGM variable names reduced from 64 to 50 characters. Please update in Build138 before upgrading to Build139.
  • Project will be auto upgraded to Build139 format:
    • All Graphics pages moved to subfolders: DocsGraphics.
    • All Trend pages moved to subfolders: DocsTrend.
    • Other.dat is renamed to Controls.Data (PGM & MP data only).
    • Projects and cfgfiles auto upgrade to always use “IF97” steam equation.
  • Scenarios saved in Build138 or earlier will not load in Build139.
