    Stiffness Matrix Element problem

    I generated an external superelement with two boundary nodes. One will be constrainted to ground, the other will be connected to another structure. Now i have to include two of these superelements in the main model at specified positions but i can't find a detailed tutorial on how to do it. Can...

    Stiffness Matrix Element problem

    Thank you rb1957 and jbrackin! I will try both superelement and GENEL methods. I have few more questions. It is possible to insert in a model multiple superelements representing the same complex part but translated and rotated to a specified position? Can I do the same with GENEL? In Femap i...

    Stiffness Matrix Element problem

    Hello, I need to represent a complex 3d model by its stiffness matrix calculated "manually" at a desired point by applying on the full 3d model unitary loads in each DOF direction and measuring displacements. I used these values in a Stiffness Matrix Element but solver returns "Element Type not...
