Experiment annotation ignored by OMC in Buildings.Fluid.HeatPumps.ModularReversible.Examples.AirToWater2D_OneRoomRadiator

Please open Buildings.Fluid.HeatPumps.ModularReversible.Examples.AirToWater2D_OneRoomRadiator from the master branch of the Buildings library and simulate it. Despite the model having ```modelica experiment( StartTime=0, StopTime=86400, Tolerance=1e-08), ``` both OMEdit and the CI simulate...

If I try to flatten Buildings.Fluid.HeatPumps.ModularReversible.Examples.AirToWater2D_OneRoomRadiator with -f, I get this error: ``` [1] 09:36:30 Translation Notification [Modelica.Media: 6549:9-6549:14]: [From here:](omeditmessagesbrowser:///Modelica.Media?lineNumber=6549) [2] 09:36:30 Translation Error [Modelica.Media: 5093:7-5094:64]: [Type mismatch in...

Jacobians in daeMode for Dynawo

OMC cannot compile Base Modelica models with functions containing local variables

Base Modelica does not have the protected keyword, hence Base Modelica functions should not have a protected section for the declaration of local (non-input, non-output) variables. Consider the following MWE...
