Hi all,
I am struggling with unconvergent problems of a 3-D node-to-surface contact.
I am modelling a subject moving on a curved beam. My moving thing consists of MASS21, LINK11, CONBIN40 and BEAM4 elements. Because its displacements follow on a curved line, so I rotate all of the moving nodes to cylindrical coordinate system by NROTAT command. And my model fails to converge!!!
From the Ansys documentation, I've learned that some of these elements operate in the nodal coordinate, and there are some warnings of using these elements in rotated nodes. However, my model seems not to violate these cautions.
Could you please help me out of this problem. Thank you very much!
