v2023.2 (June 2023 - Symmetry Update Release)

Thermodynamics
+ Error messages will now be displayed if import of a Multiflash file into Symmetry fails which will highlight possible causes of the failure.
o Added a new binary interaction parameter table in the Amines property package, "NRTL Activity Coefficient (Amines)" that replaces the existing implementation of the table. The new table contains the same interaction parameters that were previously manually internally specified for the Amines property package. Note that if any interaction parameters in these tables had been previously manually edited within a case, they would be reset to the current defaults on recall.
o Added new binary interaction parameters tables in the Amines property package, "Advanced Peng Robinson Z Factor (Amines)" and "Henry Constant Activity Coefficient (Amines)", that replace the existing implementation of these tables. The new tables contain the same Water/Hydrocarbon, Amines/Water, and Amines/Hydrocarbon interaction parameters that were previously manually specified for the Amines property package.
o An error message will now properly display when opening a case containing OLI Electrolyte Property Calculations or OLI Thermodynamic Model if a valid OLI Engine license from OLI Systems Inc. is not available.
o Hydrate inhibitor traces (< 1 ppm) are now ignored in the fluid of interest for the calculation of hydrates temperatures and pressures.
o Use of the following special characters in the naming of user defined components is now properly blocked: {, }, =, ?, ".
x Fixed an error in the calculation of the vapor phase thermal conductivity whenusing the VMG-Yaws method in mixtures that involve water.
x Fixed an issue in the Water Dew Point Special Property calculation that was causing the calculation to run out of iterations for some mixtures.
x Fixed an issue that caused the return of NaN values for the Henry Constant Activity Coefficient parameters for Sodium Hydrosulfide with Ethane which corrupted calculations in the API Sour property package.
x Fixed an issue where the solid phase failed to clear from the Solid PT flash when the composition of the solid formers is zero, which resulted in consistency errors.
x Fixed crash that was occurring in Symmetry 64-bit when importing thm files that contained empty parameters.
x Fixed the display of the Solid Formers list when a recalled Symmetry case has hypothetical or oil pseudo components that contain the following characters in their name: {, }, =, ?, ".
x Implemented a fix in the PH table type from the OLGA application of the Property Table unit operation to avoid printing "None" values when exporting the table.
x Implemented a fix to avoid assigning unknown values to a whole set of PH or PT properties when only one property calculation fails in the OLGA application from the Property Table unit operation.
x Improved the initial guess in the calculation of solid formation temperature of N2 which fixed the appearance of erroneous N2 solid formation temperature results.
x Updated the import function for .mfl files into Symmetry to recognize new keywords used to describe hypothetical components.
x Fixed enthalpy derivative calculations in the PH option of the OLGA application from the Property Table unitoperation.

Flare Workspace
+ Enabled customization of Description and contour display options for Radiation, Noise, and Temperature isopleths in the Flare Safety Manager (Flaresim Link).
o Flare Safety Manager (Flaresim) isopleth Descriptions now show results in the active unit set.
x Fixed issue to prevent Flaresim from performing calculations when Symmetry's solver is on hold.

Flaresim
o Flaresim will not attempt to check for updates when there is no internet connection. A message was added to point the user to problems with the internet connection in case they check for updates manually.
x Added missing Modified Chamberlain-H2 page in Help file.
x Applied a fix to display correct atom names and numbers for Symmetry components.
x Applied a fix to ensure VMG_components will only be reported in Combustion Results (mole and mass flow) if they are not already listed as a Flaresim standard combustion component.
x Fixed an issue of incompatible fluid engine and components selected. It now displays a warning and blocks the calculation when there is an incompatibility.
x Fixed an issue with the enthalpy and specific heat calculations when using Symmetry calculation engine as the calculation method.

Pipe Workspace
+ A message to warn the user when Orifice calculations were performed under choked flow has been added.
+ Line sizing calculation status is now shown in stream and pipe segment unit operations status.
x Fixed a problem in the Network Designer Mode which would delete sinks after merging pipes. Sinks and sources will now be connected to re-numbered nodes and show up on the UI. Sinks and sources are also re-numbered.
x Fixed Pressure loss calculations for fittings in the Pipe Workspace.
x Fixed temperature calculation for heaters and coolers in network solver.
x Fixed the line sizing calculation to update when fluid properties are modified.
x Improved convergence stability of pipe networks.

Dynamics
x Dynamics Initialization from Init Case has been fixed to ensure that the composition in unit operation holdups is properly applied.
x Fixed crash on recall of assorted old cases.
x Fixed Digital Logic > and < to be strictly < and >, rather than >= and <=.
x Fixed erroneous Selector Block/Controller back-initialization when units are not the same type.
x Fixed error message on recall of dynamics process calculators.
x Fixed Integrator hanging when trying to run after copying and pasting a dynamics flowsheet.
x Fixed Integrator window showing blank results after copying and pasting a dynamics flowsheet.
x Fixed Integrator window showing blank settings after adding a new flowsheet to a dynamics flowsheet and changing the Integrator to standalone.
x Fixed issue with unresponsive integrator when running Selector Block with default Custom Equation.
x Fixed OPC Client Fast Read From Server option to work with steady-state only variables and process calculators
x Fixed phase fraction instability on inlet streams when integrator starts.
x Fixed Ribbon Run Integrator and Open Integrator lists missing flowsheet after copy/paste.
x Fixed spurious warning message in dynamics orifices when downstream pipe diameter is effectively the same as the orifice pipe diameter.

Extensions and Links
+ OLI Link - OLI Corrosion Analyzer is now supported in material streams.
o MySep Link - MySep geometry files for the MySep Link and MySep Link Dynamics examples are now located side by side with their Symmetry case. The MySep Manager for MySep Manual examples points to the new file location.
o OLI Link - Updated titration manual example and included steps to create it.

Emissions
+ Added error messages for Fired Heating Energy User when Thermo property package doesn't contain all required components for combustion.
x Added fix to reset the displayed fuel name in energy user tab after fuels are set to default in Utility Manager.
x Correct Thermo property package names are now displayed in Fuels tab of the Utility Manager after the Fuels thermo is deleted.
x Fixed the specification of the composition in the Utility Manager when a new fuel is added in the Fuels package after a fuel had been specified in a different package.

Productivity Tools
+ Enabled the selection of unit ops from drop down list and from navigation windows for path type variables in Case Study input data window.
x Applied a fix to allow cloning of Case Studies with names consisting only of numeric characters.
x Fixed a refresh issue in the Model Regression tool to update the results tab when values in the experimental data are changed.
x Fixed an issue preventing the Case Study results to display correctly when running in Cloud mode.
x Fixed issue in Case Study Results tab that caused units tooltip conversions to be incorrect when the units tooltip configuration was not default.
x Fixed issue in Regression Cases cloned from case studies, for which the composition was not specified to the flowsheet when using the "Specify data set" button.
x Fixed issue in Regression Cases with inactive manipulated variables, for which results were not specified to the flowsheet when using the "Specify to flowsheet" button
