=== Arrow Version 11 (2025.10.31) (Build 1127) === --- Changes that may affect engineering conclusions --- 1. Fixed an issue where User-Specified Valve Equivalent Loss values would be unused and overwritten in the simulation. 2. Fixed an issue with false sonic choking messages and false flow convergence. Added several leg calculation local iteration error messages. 3. Fixed a problem with the Temperature Saturation and Superheat displayed in the Axial Point area which would only report the maximum temperature. The Inlet and Outlet values in the Pipe output were still correct. --- Important non-engineering changes --- 1. The Specify Properties button was missing on the Pipe Material Library window. 2. Improved performance related to clearing Output once Output no longer exists - some Output clearing actions were happening repetitively when they only needed to happen once per clearage. 3. Fixed issue with Split Pipe feature not correctly connecting pipes to new junction. 4. Fixed an exception that could occur when flow reversed direction in a pipe when using the Lumped Adiabatic solution method in Arrow XTS. 5. Fixed an issue that would check out a duplicate Chempak Data license seat if the Chempak Viewer was launched while Chempak fluids were already in-use in the main application. 6. The first row of the transient data table for junctions is no longer cleared when switching to event based transients. --- Miscellaneous changes --- 1. Some language localizations files had blank Workspace Layers abbreviation translations, resulting in Workspace labels with no corresponding abbreviation for the parameter value. Standard English abbreviations were added to the files for any parameters that had blanks in this field. 2. Fixed an issue where creating a Design Alert from output cells would cause system error. 3. Fixed a case where Pipe data would not copy Heat Transfer data to non-Heat Transfer pipe. === Arrow Version 11 (2025.08.29) (Build 1115) === --- Changes that may affect engineering conclusions --- 1. Fixed an issue where an Assigned Pressure or Reservoir junction with Energy Balance on and multiple pipes directed as flowing into the junction but all having reverse flow causes an erroneous temperature discontinuity between the junction and these attached pipes. 2. Fixed a bug where reverse flow restriction choked junctions in Arrow would compute results in the user-specified upstream (flow-direction downstream) pipe incorrectly, and warn of sonic choking at an incorrect junction. --- Important non-engineering changes --- 1. Fixed an issue where a Bend/Elbow's R/D value could be improperly imported from a PCF file in languages where a comma is used as the decimal mark. 2. Added more options to help load results faster when a very large number of Events are generated during runs. 3. Revised which pump curves are shown while plotting Composite Pump vs. System Curve graphs. 4. Fixed an issue where FCV inclusions in Pump Vs. System graphs were not being restored in the graph definition checkboxes after loading from a graph tab or graph list item. 5. Fixed an issue where the eLicense code entry window could appear during a license error even if a valid Registration file was present. --- Miscellaneous changes --- 1. Added display of library file path in the Edit Junctions section of Library Manager and allowed right click to copy the path to clipboard. 2. Added 'Workspace' and 'Special' buttons to Global Junction Morph panel. 3. Fixed a case when creating Design Alerts would clear output Warning messages. 4. Implement shift click on row and column headers within output data. 5. When using custom Rectangular Ducts on models built on older versions, saving the model will now preserve Duct Diameter and units associated with it. 6. Updated loading new libraries with older models. 7. Updated Workflow to display when memory constraint is reached. 8. Scenario Manager tree structure will now preserve scenario order when cloning scenarios with children and when adding scenarios within Batch Run. === Arrow Version 11 (2025.07.28) (Build 1106) === --- Changes that may affect engineering conclusions --- 1. Fixed a problem when using standard or normal mass flow rate units for an Assigned Flow junction where the first run of a scenario may not have the correct STP conditions set. The second run and reopening the scenario after a successful run would have the correct flow values. 2. Fixed issue where Hydraulic Diameter in Model Data did not match Hydraulic Diameter in Output. 3. Fixed an issue with some loss model basis areas not updating when solving for pipe scaling within GSC module. --- Important non-engineering changes --- 1. Updated eLicense DLL to address issues with hard drive serial checks and occasional hanging of application on close. 2. Updated "About" window to include additional licensing information. 3. Removed hard requirement for existence of license file for applications to open. 4. Fixed an issue where the registration file was unable to be copied from other/old locations in some cases. 5. Fixed visual validation issue with Compressor Flow/Pressure and Compression Ratio. 6. Fixed issue when exporting tanks to EPA. 7. Fixed an issue where 'Show Time Label' setting would be ignored when copying an image of an animated graph. Additionally, the label location in the image is no longer fixed and will match the location that it was placed prior to taking the image. 8. Added user option to prevent automatic snap to grid when isometric pipe drawing mode is activated. 9. Fixed errors with models containing mixtures with a large number of components. 10. Auto-rotating area changes and check valves will now automatically adjust icons to align with the flow direction and size changes at these junctions. 11. Added missing descriptions for advanced parameters and removed Disable Enthalpy Match Logic option. 12. Fixed issue with junction icons being reset after auto rotation. --- Miscellaneous changes --- 1. Fixed sizing for notes and status text boxes in Assigned Pressure form. 2. Improved image cropping when Copying Graph Image while showing raw data in Graph Results. 3. Improved visual mirroring of Magnification tool. 4. Fixed an issue where a Color Map defined with the "Show Value on Workspace Label" option could format the value incorrectly in the object's label. === Arrow Version 11 (2025.06.30) (1100) === --- Initial Release ---
