error - contact
I am analyzing a reinforced concrete frame. The connection between the elements is made through a system formed by a screw and steel plate. The connection region is filled with grout, but for initial analysis, I suppress the grout. Taking the advantage of symmetry, I modeled just half of structure.
For the numerical simulation, the following conditions were adopted:
-Element Solid65 for concrete and Link180 for reinforcement.
-The contact between the elements was defined as bonded, with Auto-Asymmetric behavior and Pure Penalty formulation (the only exception is for the region between the load suport and beam, in which the formulation is MPC).The contact tool did not indicate gap or penetration.
- For the mesh, Multizone method was employed and contact sizing option were used to refine the mesh in the contact regions.
- The load was applied in form of displacements that gradually increase with each load step (20 mm divided in 10 steps). Also, the bolt was pre-tensioned.
After solve, the program shows the following messages for many nodes:
Node 112187 belongs to element 103346. The CEINTF operation will not consider this node/element combination.
WARNING: SUPPRESSED MESSAGE
Node 26250 does not lie on or near the selected elements. The CEINTF operation produced no results for this node.
The number of ERROR and WARNING messages exceeds 10000.
Use the /NERR command to increase the number of messages.
The ANSYS run is terminated by this error. "
My questions are:
a) What are the meanings of these warnings and notes? Is it because of contact sizing I insert?
b) I saw these messages in the file0 (.err). I could not open the solver file because it is too big. Is there any way to solve this problem?
c) Is it possible to know the exact position of the nodes and elements that appear in these messages?
Any help and suggestion would be very appreciated.
Thanks is advanced!
