VehicleInterfaces.Drivers.MinimalDriver cannot be instantiated about vehicleinterfaces

[tobolar]

Maybe the usage of VehicleInterfaces.Mechanics.NormalisedTranslational.Interfaces.Flange into an expandable connector VehicleInterfaces.Interfaces.DriverInterface could cause the problem in OpenModelica. (Perhaps handling of component declared with the prefix flow in the expandable connector?)
Anyway, I can't realize such a problem using Dymola.

@dariomangoni Any update?

Well, at commit c6d3469 the situation is the same as an year ago.
OpenModelica v1.14.0-dev-26548-gc521adfdc4 is not able to simulate.
Dymola 2020 is able to simulate the model.

OpenModelica does instantiate it:

loadModel(VehicleInterfaces);getErrorString();
setCommandLineOptions("-d=newInst");getErrorString();
writeFile("MinimalDriver.mof", instantiateModel(VehicleInterfaces.Drivers.MinimalDriver));getErrorString();

But it indeed fails to simulate:

Error: Internal error BackendDAECreate.lowerKnownVar failed for ... Flange driverInterface.brakePedal

@sjoelund Many thanks. Can you further localize the problem?

@perost might be available to have a look. I don't know that much about the new frontend implementation in OpenModelica (and I'm quite busy as my teaching period just started).

It's an expandable connector issue, the new frontend doesn't yet handle augmenting expandable connectors with regular connectors correctly. It's on my todo list.

@perost Thanks.
