  • ABAQUS: Analytical Rigid components

    Hi, all. I am doing an axisymmetric 2D analysis involving analytical rigid components, made up of lines. Also, there is a deformable within. So far everything seems OK, but I suspect there is a problem with the way I constrain and manipulate the rigids.
    - I have within the parts defined a reference point
    - then i constrain the reference point to the rigid surface via a rigid body constrain
    - from there i either "encastre" the reference point on the locked (i...mmovable) parts
    - I also prescribe a predefined load on one of the reference points on the moveable part
    It just won't converge. What am I doing wrong?
