PhytoSim Change Log

Version 2.1

New features:
  • Simulation: Ability to choose the display time unit
  • Calibration: Moving window calibration
  • Calibration: Ability to enable/disable optimizer and/or objective variables
  • Uncertainty: Ability to enable/disable source and/or target components
  • Sensitivity: Morris screening global sensitivity analysis
  • Sensitivity: Extended FAST global sensitivity analysis
  • Sensitivity: Ability to enable/disable source and/or target components
  • Calibration: calibration data is only shown between start and stop time
  • Data I/O: problem importing data files with old-style Mac file endings
  • Simulation: curve legend item not visible when dragging a model component on the graph
  • Simulation: unable to edit x-axis minimum when autoscaling is turned off
  • Uncertainty: progress bar does not reset when starting a new analysis

Version 2.0.1

  • Fixes:
    • Crash when transferring calibrated source component (e.g. parameters) values to the Simulation Module.
    • Simulation graph curve settings issue for curves on the second Y-axis.
    • Issue with PhytoSim folder location in Preferences.
    • Issue with simulation Data Variables not updating their value when selecting them in the navigator.

Version 2.0

  • Changes:
    • Simplified Module Manager, all modules are now built-in (faster startup, no additional downloads required).
    • New PhytoSim software update mechanism.
    • The Help > Support dialog has been removed. Contact for support related questions.
    • Support for multiple simultaneously running PhytoSim instances per account (default is still 1 instance).
  • Fixes:
    • Mac OS X Snow Leopard is supported again.
    • Bug for workspaces within a folder structure with folder names containing special characters.
Data I/O Module
  • New features:
    • Embedded data input type. Embed data directly in the workspace: enter manually, copy-and-past or drag-and-drop selected data from text files or Excel).
Modelling Module
  • New features:
    • Fractional units, e.g. cm^3/2.
    • New unit '#', representing a count or a number of items. E.g. 20 #[plants].m^-2[ground].
    • New crop model: SUCROS1 (Simple and Universal CROp growth Simulator).
  • Changes:
    • The valueat( x, at ) function for data variables now uses the data variable independent variable for the 'at' argument instead of the model independent variable.
  • Fixes:
    • Sort order violation for algebraicVariable = previous( algebraicVariable ) or valueat( algebraicVariable, t ).
Simulation Module
  • New features:
    • Graph curves can be put on the second Y-axis.
    • Logarithmic scales on the Y-axes.
    • SUCROS1 crop model example showing embedded data inputs and advanced use of the valueat() function.
  • Fixes:
    • Scroll wheel zooming no longer zooms out beyond the graph data.
    • Potential crash when zooming in on graphs.
Calibration Module
  • Changes:
    • Faster calibration when the simulation period is only a small part of the available data period.
