How To Set ALTAIR_FMU_ROOT for Simulink Cosimulation

SUR1

Hi, 

I'm trying to simulate an FMI generated from MotionSolve in Simulink, but get an error that the environment variable ALTAIR_FMU_ROOT is not defined.

Is this something that is defined in the export from MotionSolve or something that has to be defined in the matlab environment?

Thanks,

GTT Adam

Hi @SUR1,

The Windows environment variable must be set using Windows Start » System Properties » Advanced » Environment Variables.

For more information regarding MotionSolve models as functional mockup units, please refer to the following page in the help documentation:

Hope this helps!
