Changes in Petro-SIM 3.3 Builds

Build 298 - In progress, not yet released

  • Cleaned some of the sample cases a little and added a few smarts to the dynamics assistant.
  • Added a preference option to disable journal/undo recording while the integrator is running.
  • Fixed Actual Liquid Flow stream values which in some cases return wrong negative values.
  • Fixed a null pointer crash reported in newly created PFRs when changing their volumes.
  • The Help, Check for Updates menu item will now check for and optionally initiate a download of patches.
  • The rating page, which shows nozzle elevations, will now be visible for the mixer and tee in dynamics mode.

Build 297 - Latest Released Build

  • Fixed problem recalling cases with a digital point in them.

Build 296

  • Fixed crash when using (unsupported) refinery assays in dynamics mode.
  • Enabled dragging a radio button to and from say a spreadsheet cell.
  • Cause and Effect matrix added.

Build 295

  • The valve now has a bypass valve option, as well as block in and block out valves on the main valve. On the connections page of a controller, the user can choose which actuator to control.
  • Vessel level taps implemented.
  • Dynamics initialization improvements:
    • Supports multiple regions (instances)
    • Ability to select objects in the PFD and right mouse click to send them.
    • The dynamics initialization view has a button which makes it easier to edit the list of objects.
  • The main palette will now automatically update to show appropriate objects when the user switches between steady state and dynamics mode.
  • Added an on/off switch to the air cooler.
  • Added a diagnostic message to the controller for when alarm values are ignored because they fall outside the valid PV range.
  • Changed the controller PV conditioning settings to be accessible even when the controller is not in failure mode.
  • Static heads are now enabled by default.
  • Fixed stream mass flow rates being incorrect due to a cached molecular weight value which was not being updated.
  • Fixed crashes experienced while building a case due to steady state left over Calc By information.
  • Fixed a null pointer crash.
  • The dynamics mode regular flowsheet palette now also shows the prebuilt column flowsheets.
  • Switching to dynamics mode when the dynamics assistant identifies issues now pops up a dialog box with more clearly labeled buttons.
  • Vessels using the vertical cylinder geometry and now also add a weir (though weirs are usually used in horizontal cylinders).
  • Fixed Undo to work with level taps and valve settings.
  • Several views can now be stretched to show more information, for example the navigator view which selects a controller output target.
  • The controller dll, pcntrl.dll, will now be registered during installation, to ensure that it is registered on Vista.
  • License tester and commuter manager support for dynamics licenses.
  • The desired real time factor can now be specified.
  • Fixed a crash in the Tee in dynamics mode, and added missing variables for the valve to the variable navigator.
  • The pipe unit operation now also works in dynamics mode, though it has had very limited testing.
