When investigating the three examples of the Batteries library I was running into problems with two of the examples: === Modelica.Electrical.Batteries.Examples.BatteryDischargeCharge === Error message with new frontend: {{{ [4] 12:38:18 Translation Error [/var/lib/jenkins3/ws/LINUX_BUILDS/tmp.build/openmodelica-1.14.0~dev-26599-g88bb448/OMCompiler/Compiler/NFFrontEnd/NFCeval.mo: 1401:9-1402:94]: Internal error NFCeval.evalRelationLessEq failed to evaluate ‘Modelica.Electrical.Batteries.ParameterRecords.RCData.R <= 0.0‘ [5] 12:38:18 Translation Error [/var/lib/jenkins3/ws/LINUX_BUILDS/tmp.build/openmodelica-1.14.0~dev-26599-g88bb448/OMCompiler/Compiler/NFFrontEnd/NFCeval.mo: 2459:20-2459:79]: Internal error NFCeval.evalBuiltinSum got invalid arguments (cellData2.rcData.R) [6] 12:38:18 Translation Notification [Modelica.Electrical.Batteries.Examples.BatteryDischargeCharge: 42:3-51:71]: From here: [7] 12:38:18 Translation Error [Modelica.Blocks.Tables: 11:5-13:80]: Constant cellData2 is used without having been given a value.

The example simulates OK with the old frontend === Modelica.Electrical.Batteries.Examples.CCCVcharging === Pretty much the same error message with the new frontend. The old frontend compiles and simulates fine. " defect new blocker 2.0.0 New Instantiation v1.14.0-dev-nightly a.haumer@… modelica@…
