What’s new includes:

• Added graphical representation for the convergence form
• Added a few more process units
• Improved flowsheet table functionality – you can now specify different information for each page
• Extension to enable changes in design factor (due to say availability changes) using stockpiles
• Corrected minor bug-fix on unit designers where the final step wasn’t always accepted
• A number of minor bug fixes and tweaks
• Extensive help & tutorial documentation added under “Help” tab

Version 2023.05:

• Various minor bug-fixes & improvements

• Critical bug fixed – reactions where coefficient for first component is not 1 were not being read in correctly.
• Additional under-the-hood improvements.

CycadProcess v2023 02

It’s been a while since we last uploaded a new update. We’ve been busy with many updates to various aspects of Cycad Process, including:

• Added zooming with mouse scrolling
• Added Material properties (BWI, etc)
• Extended User variables
• Extended Distribution (PSD) manager & graphing of PSDs
• Added a periodic table
• Added a line list report
• Added USGS data to component database
• Added export page to SVG file format
• Added auto-numbering of process streams
• Added auto-labelling of process streams
• Improvements to thermodynamic calculations
  • Heats of dilution
  • Aqueous heat capacities
• Our new “PFD” process units are now the default process units
  • Improved functionality
  • Improved tagging
• Added a number of process units
  • A true plug flow reactor
  • Rotary kiln
  • Phase splitter
  • Overflow unit
  • Stream splitter unit
  • CIL unit
  • Improved milling & crushing units
  • Added isotherms calculation option to SX units
  • Added to reaction options
• A host of bug-fixes, including fixes to
  • Copy/pasting of units & streams
  • Process stream & designer connectivity

This is minor release where a bug with the items selection for the flowsheet table and mass balance report were not completely split

• Flowsheet table updates when the balance is loaded
• Infrastructure upgrades continue in the background.
• Lots of progress on shifting to our new ‘PFD’ process units. Many more units added. There are a number of improvements associated with these process units and we recommend using them for new balances. Please let us know if you need a unit that we’ve missed.
• Updated stream grids to be more usable.
• Formatting of flowsheet table improved.
• Fixed a long-standing bug where reactions specified in the heat exchanger units weren’t calculated, they do now.
• Added the designer ID to error messages to make identifying/resolving designer issues easier.
• Fixed a bug in 2020.x version from correctly calculating shrinking particle/core models. (Please contact CMS for assistance should you wish to model with SPM/SCM).
• Revised calculation strategy around condenser to be more consistent.
• Fixed a bug where some reports crash if the user hasn’t specified the section name.
• A host of (not so-)minor improvements and tweaks.
