=== AFT xStream Version 2 (2023.03.21) (Build 1107) === -- Changes that affect results --- 1. Fixed a unit problem with Resistance Curves defined as Interpolated when the flow units were anything other than lbm/sec. 2. Fixed compressor Ignore Transient not being applied. 3. Fixed several issue highlighting Design Alerts in the Summary tables in the General section. The Design Alerts were correctly identified and listed on the Design Alerts tab. 4. Fixed problem with unit conversion for Temperature Superheat when graphing. 5. Allowed AFT Fluids to show and plot Temperature Saturation and Temperature Superheat. --- Changes that affect interface --- 1. Fixed an issue where loading a previous version model child scenario and re-loading the scenario would clear results. 2. Fixed an issue that would cause an exception if User Fluids were edited to have two or more additional Curve Fit Orders. 3. Fixed a problem when the first child scenario is made, the new scenario was not loaded but the parent scenario was. This was an issue introduced in October 2022. --- Other changes --- None === AFT xStream Version 2 (2022.12.12) (Build 1105) === -- Changes that affect results --- 1. Fixed issue where steady state results were not balancing the flow at branches that had pipes connected to pressure reducing flow control valves. 2. Fixed issue where negative enthalpy values from REFPROP were causing incorrect mid-calculations of static temperature resulting in branch iteration convergence issues during the transient. --- Changes that affect interface --- None --- Other changes --- None === AFT xStream Version 2 (2022.12.02) (Build 1104) === -- Changes that affect results --- 1. Fixed an issue where a Mach number exceeds maximum limit warning could be given if a local iteration produces a high Mach number before it is converged. --- Changes that affect interface --- None --- Other changes --- 1. Fixed REFPROP issue that did not affect results, but did not close handles after it was done with them. This was causing the software to crash in some instances. === AFT xStream Version 2 (2022.10.10) (Build 1102) === -- Changes that affect results --- 1. Fixed a problem where the compressor BEP is not calculated when a model is reloaded so it displayed as N/A. It now displays the correct values. 2. Fixed an issue that caused User Additional Losses to not be written to the model file appropriately. User Additional Losses would be erased when re-opening the file. 3. Fixed an issue that caused the Output Warnings to fail while loading if any triggered warnings referenced objects with the pipe symbol ("|") as part of their name. 4. Fixed a problem generating AFT Arrow Steady graph where no data would be displayed. 5. Fixed an issue with inline spray junctions where they could get into a choked flow state incorrectly when the true flow was subsonic. 6. Modified the behavior of spray junctions with no CdA Sonic defined. Previously, these sprays would mimic a choked flow calculation in exit configuration. Now, no spray junction will do a choked calculation unless specifically directed to by the user via provision of a CdA Sonic. Both before and after this change the user was/will be presented with a Warning. --- Changes that affect interface --- 1. Fixed an issue that could cause Relief Valve Pressure Units to be reset to default after opening the property form in specific configurations. 2. Fixed an issue that caused Output Control Format files to be written incorrectly. --- Other changes --- 1. Put in a fix for the Chempak eLicense check on model run === AFT xStream Version 2 (2022.06.08) (Build 1100) === --- Initial Release ---
