Hi. When I use these quadratic elements with modal analysis ANSYS seems to ignore he midside nodes and produces the same frequencies and modeshapes as it does with the linear elements.
I've seen this with tet, pyramid and prism. Hex is a bit different but the quadratic ones still don't deflect...
Usually a DC motor at constant voltage has maximum torque at stall and zero torque at maximum speed, with a linear relationship between them. So if you assume the torque and speed ratings are the maximums, you can find that the low-speed torque is 600in-lb - N * in-lb/RPM.
