Problems about the Contact Roller of the 3D FE Model in ADINA
Dear everyone,
Recently I am running a 3D FE model in ADINA to
analyse the elastic-plastic fracture behaviour.
A three-point bending specimen was modeled and the specimen was
supported by a contact roller.
Here is the problem:
In a rather small loading (load line displacement was about 0.1mm),
the program indicated that “the mesh is
too distorted” and stopped running. It also showed “No convergence” and stopped if the small strain formulation was
used.
