According to my calculations, I need to have 1900 N.m torque from the turbine. But in the graphic window I get this patternal instability of torque. What can cause an uncertainty like that? Shouldn't I have a linear approximation to 1900 N.m instead of this? I pondered about that, but couldn't come up with an idea.
