Cycad Process®

(version 2021.04)

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.

What is Cycad Process®?
Cycad Process® combines process simulation with sophisticated drawing capabilities to produce detailed engineering diagrams and reports. The package allows you to draw the process flow diagram or process block diagram and calculate the mass and energy balance.
