Hi, thanks for the suggestion, but the problem persists. I have changed the version of the Visual Build to 2019 and I get the following error:

Building "IndustryExamples.AutomotiveTransportation.Driveline.DrivelineModel" as experiment "DrivelineModel 1" started at 09:37:13 Notification: The initialization problem is underdetermined, the following variables were chosen to be initialized from their start values: transmission.clutch1.phirel, body.lumpedBody.v, body.lumpedBody.s, transmission.TCU1.firstOrder1.y, engine.smoothingFilter1.firstOrder1.y, driver1.pidControler.I.y, driver1.pidControler.D.x, engine.firstOrderFilter.y, driver1.firstOrder1.y, engine.Jm.w, fuelGauge.consumedEnergy, driveShaftRight.wrel, driveShaftRight.phirel, driveShaftLeft.wrel, driveShaftLeft.phirel.
