Modelica-Buildings Library (master): Simulation fails at initialization because of Real parameter expressions evaluated to false by the OB

How can it be that pure functions only are involved in this case, which involves the reading of a file from the Resources directory? To me, a function that reads...

Modelica-Buildings Library (master): Simulation fails at initialization because of Real parameter expressions evaluated to false by the OB

Aha, sorry, I did not analyze that in detail. Frontend behaviour looks good, then. @phannebohm, @kabdelhak the ball is in your field. Specifically: why is `buiWitETS.bui.facMulHea` evaluated to 0.0/false by...

Modelica-Buildings Library (master): Simulation fails at initialization because of Real parameter expressions evaluated to false by the OB

@phannebohm I'm not sure why this happens to you. I just tried with one of the latest OMC nightly builds: - open OMEdit - install Buildings 11.0.0 - open Builindgs...

Modelica-Buildings Library (master): Simulation fails at initialization because of Real parameter expressions evaluated to false by the OB

I also ran this script from the command line ``` loadModel(Buildings, {"11.0.0"}); getErrorString(); setCommandLineOptions("-d=nogen"); getErrorString(); setCommandLineOptions("-d=initialization"); getErrorString(); setCommandLineOptions("-d=backenddaeinfo"); getErrorString(); setCommandLineOptions("-d=discreteinfo"); getErrorString(); setCommandLineOptions("-d=stateselection"); getErrorString(); setCommandLineOptions("-d=execstat"); getErrorString(); setMatchingAlgorithm("PFPlusExt"); getErrorString(); setIndexReductionMethod("dynamicStateSelection"); getErrorString(); simulate(Buildings.DHC.Loads.Heating.Examples.BuildingTimeSeriesWithETS);...

Modelica-Buildings Library (master): Simulation fails at initialization because of Real parameter expressions evaluated to false by the OB

I also did the same by loading the 12.0.0-dev version from my file system (I have not installed it, because I need to be able to update it constantly), but...

Modelica-Buildings Library (master): Simulation fails at initialization because of Real parameter expressions evaluated to false by the OB

I'm using v1.25.0-dev-414-gb97bfa95a2. As I understand, more recent commits only affected the NB. I don't know what to think.

Modelica-Buildings Library (master): Simulation fails at initialization because of Real parameter expressions evaluated to false by the OB

@kabdelhak can you reproduce the issue on your computer?

Modelica-Buildings Library (master): Simulation fails at initialization because of Real parameter expressions evaluated to false by the OB

@kabdelhak, I ran the model with this script: ``` loadModel(Buildings, {"11.0.0"}); getErrorString(); setCommandLineOptions("-d=nogen"); getErrorString(); setCommandLineOptions("-d=initialization"); getErrorString(); setCommandLineOptions("-d=backenddaeinfo"); getErrorString(); setCommandLineOptions("-d=discreteinfo"); getErrorString(); setCommandLineOptions("-d=stateselection"); getErrorString(); setCommandLineOptions("-d=execstat"); getErrorString(); setCommandLineOptions("-d=evalParameterDump");getErrorString(); setMatchingAlgorithm("PFPlusExt"); getErrorString(); setIndexReductionMethod("dynamicStateSelection"); getErrorString(); simulate(Buildings.DHC.Loads.Heating.Examples.BuildingTimeSeriesWithETS);...

Modelica-Buildings Library (master): Simulation fails at initialization because of Real parameter expressions evaluated to false by the OB

@kabdelhak the behaviour I'm getting is consistent with what happens with the CI. Maybe there is something wrong with the package manager in your installation, which I understand is probably...

Modelica-Buildings Library (master): Simulation fails at initialization because of Real parameter expressions evaluated to false by the OB

I just diff'ed my flat model output with @perost's, and the two log files are **identical**, except for the numerical values of the execstat output, which is of course much...
