The moment of inertia for a channel section in DM is not the same as in mechanical. A comparison between the channel section and an identical user defined section shows also the difference. In mechanical the moment of inertia for the channel section matches the moment of inertia of the user defined section. Is the moment of inertia computation in DM for the channel section a defect?

Yes, hand calculations also show that the value in DM is incorrect in 14.0. This was reported in defect 22858.
