• The "Variation Tables" property of gaps and channels has been renamed to "Geometry."
• The "Geometry" pop-up menu item was added to gaps and channels to open the "Geometry" dialog.
• The gap top-down view drawing was changed to a standard size that is not dependent on the width of the gap nor the "Pixels Per Meter" property of the view.
• Logic was added to the Vessel 4.4 ASCII export to sort the exported channel numbers.
• The variation table export (vessel 5.3) was changed to use the correct number of entries per card (8) rather than 12.
• An issue was resolved in the group 7 (vessel 7.2) import that would cause the last entry on each card to be lost.
• An issue was resolved in the export of vessel card 7.2 that allowed too many values to be exported on a single card.
• An issue was resolved in the group 13 boundary condition completion and connection editing dialogs that would improperly constrain the level to 1->NONODE+1.
• The drawing logic for group 13 boundary conditions of type 1 was updated to display as a cell connection rather than an interface connection to a channel.

• The group 17 ASCII import/export logic was corrected and changed to handle ILV_IG references 1->NONODE+1.
• The group 18 file reads and file writes editors were updated to allow axial levels 1->NONODE+2.

Version 0.2.6 - Released 7/8/06:

• User Defined Constant creation logic was added to the ASCII import routines to handle the inclusion of replacement variables in the body of the imported deck. To be properly imported these variables must be specified for floating point fields, must fit within the columns defined by the input manual and must start with a "$". (e.g. $VAR1, $PIE3, etc.) NOTE: Variables imported in this way are assigned a value of 0.0.
  
  To support this feature, an export "ASCII with Numerics" menu item was added as well as the LITERAL parameter for the export batch command. These additions allow a model to be exported including the names
  (rather than the values) of the included user defined constants.
  
• An issue was resolved that prevented group 7 flow blockages from being properly reconnected during copy/paste, section NONODE editing and channel section reference editing.
• An issue was resolved in the group 16 export logic that would cause the kinetics heat structures and volumes to be intermixed.

• An issue was resolved in the section IVARDX table export that would cause the trailing linefeed to be omitted.
• An issue was resolved in the channel KGAPA/KGAPB editor that prevented any changes from being saved to the channel when pressing OK.
• An "Interface Badge Fraction" property was added to the COBRA preferences that can be used to specify the fraction of a drawn channel cell that the flow blockage and loss coefficient badges(shading) will use.
• The channel/gap variation table editor was updated to include:
  • a visual indication (up and down arrows) for rods that span multiple sections.
  • node selection via the drawing at the top of the editor or the table at the bottom of the editor.
  • indicators for vertical mesh boundary condition connections and coupling connections to interfaces (left) or nodes (right)
• An issue was resolved that would prevent section related views from updating when changing NONODE.

Version 0.2.5 - Released 7/2/06:

• An import error was corrected for Group 13.11 ALINE input.
• An error was resolved effecting export of head flow curves and unheated conductor data. These will now ouput correctly in British units.

Version 0.2.4 - Released 6/30/06:

• An Edit button was added to the dialog used to select boundary forcing functions.
• The connection/drawing logic for boundary conditions of type 1 was updated to ensure that the specified node numbers are 1 to NONODE+1.
• Coupled boundary conditions (group 18) were updated to ensure that the specified node numbers are 1 to NONODE+2.
• An issue was resolved group 19 ASCII import routines that prevented the import of single quoted names.
• Group 19 was renamed to Group 20.
• An issue was resolved in the group 17 ASCII import routines that would cause the import to fail if ILV_IG was specified.
• An issue was resolved in the group 5 variation table editor that would allow editing of node 1. This editor is available via the group 5 node in the Naviagor.
• A channel-centric variation table editor was added to the channel component that includes a detailed drawing of the channel and related components (such as rods and channels above/below).
• The channel drawing logic was updated to include shading at each interface location for loss coefficients (green) and grid spacers (dashed blue). In addition, the flow blockage (type 3 boundary condition) annotations were updated to match that of boundary condition component drawing (dashed purple).
• The channel drawing logic was updated to connect coupled boundary conditions to the top (for node=NONODE+2), bottom (for node=1) or the side of the connected cell (2 <= node <= NONODE+1).
• An issue was resolved in the gap drawing code that would incorrectly use variation table levels 1 to NONODE (rather than 2 to NONODE+1).
• An issue was resolved that prevented the import of group 1 PREF values.
• An issue was resolved in the channel ASCII import logic that prevented the import of channels with more than one KCHANA/KCHANB (Vessel 2.3) card.

Version 0.2.3 - Released 6/16/06:

• The channel drawing logic was updated to use a dark red for channels are connected to Rods and purple for those that are connected to unheated conductors.
• The channel drawing logic was updated to allow boundary condition connections to be placed at appropriate locations around the channel.
• The vertical mesh cell boundary condition drawning logic was updated to include visual indication of the type of boundary condition.
• A drawn component was added for the coupled boundary condition component.

• An issue was resolved in the group 14 PRINTC, PRINTG, etc. tables that would erroneously add all available channels, gaps, etc to the table on import if the size of the table being read was 0. The current behavior matches the input manual in that an empty PRINTC table indicates that all channels should be printed.
• An issue was resolved that prevented deleted components from being removed from the group 14 PRINTC, PRINTG, etc. tables.
• A completion dialog was added for the vertical mesh cell boundary condition component.
• An issue was resolved that prevented some of the COBRA "Check Model" model validation checks from being executed.
• A check was added to vessel 13.12 import to indicate missing gap components.
• A "Scale Selected Factors" button was added to the variation table editing dialog.

Version 0.2.2 - Released 6/9/06:

• The boolean (check box) editor used in COBRA tables was replaced with an easier to use, single-click editor.
• Logic was added to recall the previous location and size of many table editing dialogs.
• An issue was resolved that caused error messages to be displayed in the Message Window at times other than the "Check Model" routine.
• Various model validation and consistency checks (and their corresponding error messages) were updated and improved.
• The label text displayed for several custom editors (such as the loss coefficients editor) was updated to include
  more information about the current values.
• The ASCII I/O for groups 18 & 19 was modified to read/write just after group 17 rather than after the time domain data.
• Several issues were resolved in the constraint checks for the Connection Tool when used to connect Channels, Gaps and Boundary Conditions.
• An issue was resolved that prevented connections between Channels, Gaps and Boundary Conditions from being drawn in 2D views when the geometrical data for either side of the connection was not completely defined.
• Paste Special capability was added to allow the pasting of Channels with a user-specified section offset. This can be used (with cut) to move Channels (and their related components) from one section to another or from one model to another.

Version 0.2.1 - Released 6/5/06:

• Added the Split Section feature as a menu item available in the right-click pop-up menu of Sections.
• The Show ASCII feature was updated for all group nodes in the Navigator. These ASCII views now include the exact same formatting and content as a fully exported input file.
