=== AFT Fathom Version 13 (2024.04.16) (Build 1115) === --- Changes that affect results --- 1. Fixed issue where changes to Wasp-Durand options on Slurry Definition panel did not clear output when the Analysis Setup Window is closed. 2. Fixed issue where non-water based slurries could deviate from expected results. 3. Modified messaging for Laminar or Non-Newtonian flow. Now, messages will be generated for any pipe in the Laminar range, rather than indicating anything about apparent correction strength. --- Changes that affect interface --- 1. Limited the number of multi-scenario output to 250 scenarios to avoid file and display errors. 2. Improved visualization of Design Alerts when graphed in Profile plots. 3. Fixed an issue where pipes would not show in the Overview Map at close zoom levels. 4. Updated Printer Page Layout and Print Area Preview on the Workspace to have more clear behavior and options. 5. Improved performance of Workspace Edit operations (Cut, Paste, Duplicate), especially for large models. 6. Added junction numbers to the Edit->Select Shortest Path menu labels for clarity. 7. Fixed issue where auto arranged tees failed arrangement for Miller flow combining or Miller flow splitting tees. 8. Fixed an issue that caused Undo to not operate correctly for Annotations. 9. Limited the number of multi-scenario output to 250 scenarios to avoid file and display errors. 10. Only show modified pump curve up to modified runout value, if such value exists. --- Other changes --- 1. Fixed an issue that caused just the first graph in stacked graph configurations to be saved to a file by using the File->Save Graph As... dialog. 2. Fixed an issue where SSL models would not apply scenario inheritance correctly. 3. Fixed an issue where the app couldn't launch under certain regional conditions due to pathing problems to the INI file. 4. Fixed an issue where EPANET objects with IDs greater than the integer limit (2,147,483,647) would cause an arithmetic overflow exception when imported. === AFT Fathom Version 13 (2024.02.05) (Build 1111) === --- Changes that affect results --- None. --- Changes that affect interface --- 1. Fixed a problem when pasting in values to the Intermediate Pipe Elevation table where the final point-to-point value was not updated, which could double the length of the pipe. 2. Profile Plot titles will now display the first and last pipe numbers of the selected path, rather than the lowest and highest overall pipe numbers. 3. Fixed a problem when going to Select Special from Output Control or Model Data if Zero Length Connectors were not being displayed in the list. 4. Fixed a problem during a batch run where the results would not be saved to a text file when this option was selected. 5. Improved performance when a large number of objects are deleted from the workspace or bulk modified in Analysis Setup. --- Other changes --- 1. Fixed an issue where changing Scenarios while the Recovery File or Auto-Save was running could cause corruption of some model/object data. 2. Fixed a problem causing the Warning and Design Alerts to not be exported when using the Preformatted option. 3. Updated the descriptor for Stainless Steel Tubing, 1-3/4 from 14 BWG to 16 BWG to match wall thickness value. This would not change the engineering data but may cause some pipes to become undefined if models are using this. === AFT Fathom Version 13 (2023.12.12) (Build 1110) === --- Changes that affect results --- 1. Fixed an issue in XTS where the system could dynamically enter a state isolating regions from a reference pressure, but continue solving. This state cannot be solved for, and the steady-state solver is halted from proceeding when this is encountered. This check was added to the transient solver - the run will now halt mid-transient if this occurs. 2. GSC: Fixed some problems which caused the Valve Open Percent to not work properly. It would not find a solution because it would not change the Variable value correctly. 3. Updated a warning to inform users when slurry flow is likely to form a stationary bed in certain pipes, and allow that to apply for the 4CM and Wasp-Durand slurry models. 4. GSC: When Pipe Scaling was used as a variable, it would be reported in the GSC Variable tab in the output as 100x the actual value. This did not affect the results other than the display. 5. Fixed an issue where the 4-Component Model referenced the Wilson Addie Clift stratification ratio when it should be set to 1 instead. 6. Fixed an issue that caused calculated Fluid Properties to be incorrect when the Environmental Properties were changed. 7. Fixed a problem reporting the K factor for sprays where the direction of the pipes were not "properly" oriented compounded with some being closed. --- Changes that affect interface --- 1. Fixed an issue where User Default font settings in Global Layer Settings were not being saved or loaded properly in languages where a comma is used as the decimal mark. 2. Added more robust error handling for file manipulation errors commonly encountered in Library Browser. 3. Fixed a problem which disallowed Global Editing buried pipe information. 4. Fixed an issue that caused recorded animations to not prompt for a save location. 5. Made error reporting improvements in Graph Results Multi-Scenario graphs. 6. Fixed an issue that caused Layer Label Control Parameter Lists to load incorrectly while using certain language translation files. 7. Fixed an issue where objects duplicated using Duplicate Special could be hidden on the All Objects Layer. 8. Fixed an issue with EPAnet export that caused models with Exit Relief Valves to fail the export. 9. Fixed an issue when choosing the "Handbook" Loss Source option for Valves was sometimes throwing an IndexOutOfRangeException. 10. Fixed an issue that caused Select Working Fluid in the Startup Form to fail when a Chempak fluid was selected. 11. Fixed an issue that caused multi-parameter graphs with Elevation, EGL, or HGL selected as the first parameter to be combined for inappropriate secondary variables. 12. Added import of junction image sizes and pipe thickness to Workspace Layers Import. --- Other changes --- None === AFT Fathom Version 13 (2023.10.18) (Build 1101) === --- Changes that affect results --- 1. Made several improvements to Variable Fluid Properties so that fluids across pipes are handled more consistently across Analysis Setup, Pipe, and Global Pipe Edit usages. 2. XTS: Added event messages when Relief Valves open or close. 3. Making changes to Design Alerts no longer requires clearing Output to see those changes in results --- Changes that affect interface --- 1. Fixed an issue with annotations using the "Line Show" property not being saved properly when hidden on the Workspace --- Other changes --- None === AFT Fathom Version 13 (2023.09.14) (Build 1100) === --- Initial Release ---
