None. >> Changes to data management that could impact results << 1. Fixed a problem where the user-defined fittings and losses saved in a model would be lost when the databases were reset (loading new scenarios, clicking OK in the Database Manager, etc.). >> Changes that do not impact results << 1. Fixed an issue where the "Convert to Annotation" menu item is sometimes disabled in graphs. *** Changes for Version Date 2018.09.06 *** >> Changes to computation logic that could impact results << 1. None. >> Changes to data management that could impact results << 1. Fixed a problem with compressors using X-Y interpolated power data which would cause the power to be zero and the efficiency to be 100%. This changed the compression process calculations and fluid properties. >> Changes that do not impact results << 1. Fixed an issue with compressors using X-Y interpolated which caused the Compressor/ Fan Property Window to not load and display. 2. Improved the logic for initial guesses to prevent the initial guess for pressure and temperature from being outside the valid range for the selected fluid. 3. The Compression Thermodynamics data was being hidden if the Fan option was selected. 4. Updates to PCF/CAESAR II Neutral file import. 5. Fixed a bug when using multiple pipe draw mode in Isometric the red guide lines were not appearing. 6. Fixed an issue when in Isometric on the Workspace, Visual Report would show a standard grid. 7. Fixed an issue with the formatting for the Crosshair label on Graphs. 8. Fixed an issue where Excel Export would crash when exporting a profile graph with Junction labels turned on. 9. Excel Export would erroneously report that data was overwritten when exporting "Other - All General Information" data. This has been fixed. 10. Selected Excel Export Items that were potentially available to export but not in the current scenario (denoted by a *) could cause the Excel Export Manager to stop functioning correctly. This has been fixed. *** Changes for Version Date 2018.09.10 *** >> Changes to computation logic that could impact results << 1. None. >> Changes to data management that could impact results << 1. Fixed a problem introduced in the 2018.09.06 version that didn't allow Fittings & Losses to be entered for a pipe. This did not affect any existing values entered. >> Changes that do not impact results << 1. None. *** Changes for Version Date 2018.10.11 *** >> Changes to computation logic that could impact results << 1. None. >> Changes to data management that could impact results << 1. The maximum and minimum static temperature reported in the General Section of the Output was reporting stagnation temperature. This was fixed. This is only a display issue. 2. Fixed a problem in the Compressor/Fan Summary where the dP Static value was reporting the dP Stagnation value. This is only a reporting issue in the summary, the value in the general junction area is correct. >> Changes that do not impact results << 1. Fixed an issue that sometime would clear the Apply check mark for Excel Exporting. 2. Minor changes to background color dialog window for annotations. 3. Fixed annotations missing background colors from older models. 4. Added "Ignore Fitting Lengths" option for PCF and CAESAR Import. 5. Fixed an issue with CAESAR Neutral File import for inner diameter. 6. Converted EPANET import to use the import preview window. 7. Fixed an issue where drawing an annotation can result in an annotation that is too small. 8. Fixed an issue where the Excel Export Manager was not displaying its bottom grid correctly. *** Changes for Version Date 2018.11.08 *** >> Changes to computation logic that could impact results << 1. None. >> Changes to data management that could impact results << 1. None. >> Changes that do not impact results << 1. Fixed an issue when connecting a pipe material database it would be listed under the regular engineering databases and not with the pipe materials. 2. GIS importing now uses a preview window, similar to PCF importing. 3. The font formatting in the System Properties window in Chinese - Simplified versions of Windows has been fixed. 4. Fixed an issue where EPANET files were not importing elevations correctly. 5. Fixed an issue where EPANET files were not exporting or importing check valve Cv values. *** Changes for Version Date 2019.01.02 *** >> Changes to computation logic that could impact results << 1. None. >> Changes to data management that could impact results << 1. Fixed a problem when splitting a pipe, the downstream elevation and pipe fitting losses (if specified) were not being kept. >> Changes that do not impact results << 1. None. *** Changes for Version Date 2019.03.11 *** Initial release for new GSC DLLs. >> Changes to computation logic that could impact results << 1. None. >> Changes to data management that could impact results << 1. Fixed a problem when splitting a pipe, the downstream elevation and pipe fitting losses (if specified) were not being kept. 2. Corrected an issue transferring data from the "Guide for Xt, FL, and FD..." window back to the Valve Properties window when the decimal symbol is set to "," and the digit grouping symbol is set to "." 3. When using a REFPROP fluid and opening a model with previous results, and a K factor valve loss, the output would not be properly loaded and would create an error. This has been resolved. >> Changes that do not impact results << 1. Changed Zoom behavior when objects are selected in the Workspace. 2. Fixed an issue when editing an annotation's text and then clicking 'Cancel' the text will still be changed in the annotation. 3. Fixed an issue where 'Copy Graph Image' and 'Record Animation' would not work right when the Windows Font Size is set to anything other than 100%. 4. Fixed an issue when duplicating an annotation the 'pre-paste' window shows up behind the annotation. 5. Fixed an issue where some Pipe length values not imported using the PCF Import. 6. Minor bug fixes when overwriting Graph List items. 7. Fix for Profile Graphs when flow direction changes along a path. 8. Made a minor change to the behavior of the 'Global Search' when searching for text items. 9. Fixed an issue with EPANET import for computers with different Regional Settings *** Changes for Version Date 2019.03.28 *** >> Changes to computation logic that could impact results << 1. None. >> Changes to data management that could impact results << 1. CRITICAL: Starting in the October 2018 releases, an additional field was added to the Control Valve data. This was placed in the wrong area and had the potential to corrupt the data that followed. This has been fixed. Models that were opened in the affected releases should have the data for the Control Valves rechecked. >> Changes that do not impact results << 1. Fixed a problem with Duplicate Special when duplicating pumps. 2. Fixed an issue with the Pre-paste object when handling large areas on the Workspace. *** Changes for Version Date 2019.07.15 *** Initial release for ANS Module. >> Changes to computation logic that could impact results << 1. Heat transfer design factors were not being applied correctly to user specified external convection coefficient values. This has been corrected. >> Changes to data management that could impact results << 1. None. >> Changes that do not impact results << 1. Fixed alignment of Junctions and Pipes when copying/pasting/duplicating in Isometric. 2. Fixed an EPANet Import issue when valves have a 'setting' that is not numeric. 3. Made improvements to zooming in the Workspace Overview Window. 4. Minor Fixes to PCF Import. 5. Changed the name of refProp H2O to Steam, as opposed to Water, for gas systems. 6. Improved EPAnet import capabilities and issues with certain pipes failing to import. *** Changes for Version Date 2019.10.04 *** >> Changes to computation logic that could impact results << 1. None. >> Changes to data management that could impact results << 1. None. >> Changes that do not impact results << 1. Fixed a Global Edit problem when changing pipes to use buried pipe heat transfer where it was requiring an external convection coefficient. Opening the pipe and clicking OK will resolve this as well. 2. Fixed an inconvenience where two confirmation messages would be given if a junction was put on the Workspace and there were child scenarios with output. 3. Updated the Excel Import workbook to include heat flux, heat rate, ambient temperature, ambient fluid velocity, soil temperature and buried pipe depth. 4. Fixed Print Preview to force expanding of collapsed grids in Output. *** Changes for Version Date 2019.12.11 *** >> Changes to computation logic that could impact results << 1. Resolved internal REFPROP error when using valve Cv loss. 2. Improved calculation precision for Chempak with supercritical fluid near M = 1. 3. Some calculations of dynamic pressure have been corrected, affecting Compressor DP when static pressure curve is entered and some PRV & PSV calculations. >> Changes to data management that could impact results << 1. Fixed problem with the Cost Report loading which would delete the settings in Output Control when a scenario was loaded so nothing would be in the report. >> Changes that do not impact results << 1. If a preferred unit was set as a default other than the application default, it would be overridden when the application was restarted. This was fixed. 2. The Visual Report window was not displaying user-selected colors for pipes correctly the first time it was loaded. This has been fixed. 3. The Excel Export was not properly exporting Cost Report data. This has been fixed.
