v10.2.12

What's new in this release

• spreadsheet pickers write formulas with the parser's argument separator (#101)
• new columns start with zero pressure drop; Avalonia editor shows and edits the stage pressures (#96)
• Nested Loops bubble point keeps a converged root (#97)
• Nested Loops PT all-vapour shortcut checks the equation of state (#100)
• the bubble-point solver's search on the bottoms rate stays inside the feed and takes the temperature-step fallbacks
• bubble-point solvers report the reboiler fraction of the reboiler spec component
• Nested Loops bubble points keep a confirmed retry; v2 checks its ideal fallback (#97)
• store spreadsheet formulas and numbers independently of the locale
• dwsim-mcp postinst reads the options without sourcing the config (#102)
• Flowsheet unit operation finds its sub-flowsheet when loaded through the automation interface
• PR #91 follow-up: net472 build and Flash_PH_1 bracket fallback
• add, remove, rename and edit Python Script variables in the cross-platform editor (#103)
• flowsheet Delete, Backspace and Ctrl+C/V/A act on objects only from the canvas
• CAPE-OPEN property package selection in the cross-platform UI (#104)
• CAPE-OPEN 1.0 phase properties use the mapped phase label
• CAPE-OPEN fugacity, heat capacity and 1.0 compound list
• ChemSep vapour thermal conductivity above 1 atm
• Copy Data to Clipboard on property tables and charts in the cross-platform UI
• distillation curves and petroleum product properties of a stream
• secondary specifications on the rigorous column
• cold flow utility, depressurization restore and pseudocomponent viscosities
• list external column solvers only on distillation columns
• external column solvers for absorbers; distillation curve fixes
• free water product on the distillation column
• bubble-point solver checks the bubble points before accepting the wide-boiling path
• immiscible-water PT flash with water-unsaturated vapor (issue 112)
• conversion reactor heat of reaction from the signed extent
• anaerobic digester option to saturate the biogas with water vapor
• run every spec tied to an object, not only the last one attached
• biomass compound creator sets Pc from the molar volume
• CAPE-OPEN socket rebuilds the overall liquid whatever the liquid phase label (issue 114)
• pipe wall materials recognised in every interface language
