Hi Angelo,

Where's the error message?
Try to use an .mos script to run your model and after every command put getErrorString();
Try to run your script using omc with line command. After, try to find test_circuit.log. This way you will have more expressive errors.

Regards,

Jawhar

This is the log file after omc +s synchronous6.mos
