Stiffness matrix
Stiffness matrix
(OP)
Hi,
I have a question about the stiffness matrix?
I am trying to model a beam, and this beam is fixed supported,so this gives a rotation angle of zero. But nou I want to model an elastic fixed rupport, so the rotation angle isn't zero.
Where and how is this definied in the stiffness matrix, or how solve this problem?

RE: Stiffness matrix
you can use the Combin7 element as a revolute joint whith defined stifness.
