5853	-d=-disableDirectionalDerivatives Fails	bode-h@…	Andreas Heuermann	"Hello,

i want to enable the directional derivates in generated FMU.

To do so, I set under tools -> options -> Simulation the flag 

''-d=-disableDirectionalDerivatives''

Saving and generating the FMU via Data - Export - FMU gives me an FMU file. 

Opening it in Python (PyFMI) returns the Error:

''FMUException: This FMU does not provide directional derivatives''

''Watching the flags shows following result: 

model = load_fmu('simuflag.fmu')

model.get_capability_flags()
Out[44]: 
{'needsExecutionTool': False,
 'completedIntegratorStepNotNeeded': False,
 'canBeInstantiatedOnlyOncePerProcess': False,
 'canNotUseMemoryManagementFunctions': False,
 'canGetAndSetFMUstate': False,
 'canSerializeFMUstate': False,
 ''''providesDirectionalDerivatives': False,'''
 'completedEventIterationIsProvided': True}''


Why is this flag still set as false? 
Any bug, or mishandling by myself?

Best regards

Henrik
