Change Log

Version 2.4.2 - Released 2/10/19:

  • The radiation enclosure surfaces editing dialog was updated to include a horizontal scroll bar for the view factors and to expand the table cells to display the entire view factor values.
  • The lower head component has been updated to only write the RN in and out transfer process references if they are set.
  • The Initialize Core Dimensions dialog has been updated to ensure that all fields are visible when the dialog is opened under Windows.
  • The core nodalization menu item for the core component is disabled unless the core is active.
  • The external sources dialog for control volumes has been updated to support multi-editing of source data and to resolve an issue that would prevent undoing changes made to external sources.
  • The ASCII export for control functions in models set to MELCOR 2.1 has been updated to suppress the boundary conditions card (CF_ULB) when the boundary input mode is set to "No boundary input".
  • The core package has been updated to support activating the core eutectics model without adding any pair melt entries.
  • The 1.8.6 ASCII I/O routines for the external mass and energy sources data was updated to use the water index property to build the card number for the associated water source card.
  • The Initialize Core Dimensions dialog has been updated to ensure that all fields are visible when the dialog is opened.
  • The control function argument dialog has been updated to resolve an issue where pressing the create button in the input selection dialog would add all of the components in the model to the list of valid selections.
  • The control function argument dialog button that adds a constant value to a control function has been updated to have a visually distinct icon and to include tool tip text that identifies the buttons behavior.
  • The core cell control range has been updated to correct the Upper Core selection criteria display label and export text.
  • The heat structure ASCII I/O logic has been updated to resolve an issue where importing a controlled surface temperature boundary condition with optional values included would produce an error.
  • The RN package generalized release class multipliers have been updated to allow specifying a control function for the Burst Multiplier, Diffusion Multiplier and the Cumulative Burst/Diffusion Multiplier fields.
