Hello,
I'm hoping someone can help.
I've got a dynamic model of a turbine made up of 3 blades attached to a hub. I'm applying a load to one of the blades to make it rotate.
I would like to measure the moment at the hub to check that it matches the force I've applied multiplied by the distance.
I've done this with a static model by fixing the hub so it can't rotate and then by getting the reaction moment. However I'd like to find the moment during a dynamic load step.
I've tried requesting a history output of the concentrated moment about the z axis using the CM3 command but this isn't working for me. It's doesn't even show up in my output database. Any ideas?
Many thanks
George
