extra information about Corotational transformation

Post by hshoar » Thu Jan 23, 2014 12:15 am

Hello,

can anyone explain a bit more about Corotational transformation? my main problem is about this sentence written in command manual: "Currently the transformation does not deal with element loads and will ignore any that are applied to the element". what exactly will happen according to this notice?
I would greatly appreciate if you can give me more information about this.

Member, e.g., distributed, loads are ignored because they can either be applied in the local or corotating frame of reference. We simply didn't implement either option!

May i ask a question too: When we use Corrotational transformation, do the displacements obtained from Recorders concern global or local coordinates?

The node recorders will give you responses with respect to global coordinates
