4977	Directional derivatives error (FMU for model exchange)	contacto@…	Willi Braun	"Hello,

I'm using FMUs generated by OpenModelica from FMPy and PyFMI.

When I try to get directional derivatives from the FMUs, there are crashes (with both libraries).

The FMUs are generated from console: c:\openmodelica1.13.0-dev-64bit\bin\omc -n=1 -d=-disableDirectionalDerivatives --postOptModules+=wrapFunctionCalls fmu.mos > error_fmu.txt 2>&1

Files are attached.

Am I doing something wrong or could it be a bug in the FMU code?

Thanks!!!
