Steel C Beam Meshing
I'm modeling two C Beams that has a 10 ton force right in the middle, also with a reinforcement piece in the middle. I want to model this system with a very refined meshing. What I'm doing is:
1.- In Design Modeler I used the split tool to create bodies with a "sweepable" shape.
2.- In Design Modeler, I create a new part for each beam, also I used the "Shared Topology" tool to create a better match between elements and nodes. I also use the "imprint" setting.
3.- In Ansys Workbench I see that every body has the right contacts, all set as bonded.
4._ I create the force (98.1 kN) in a small body that I created to simulate a point force. The beam has a length of 0.75 m, and this element is only 5 mm.
5.- I create the supports (cylindrical).
6.- Then I used sweep methods and edge sizing to get hex elements. I was tought that these are the better elements for "cubic" bodies.
So here is the thing: As I create the meshing "upgrade" the simulation stops running. I get the error of the image. As it is a unkown error, I open the Solution Information and I read the next error:
*** ERROR *** ELAPSED TIME = 6.544 TIME= 23:05:36
The behavior of target elements (e.g. 46005, 46004) specified by real
constant 129 are not consistent. Some of the elements belong to a
rigid surface, while others belong to a deformable surface. If
intended to be a deformable pair, ensure that each target element has
full association (shares all the nodes) with the underlying solid
element.
*WARNING*: The program could not find attached solid element for
contact element 45896. Check the element connectivity data.
*** ERROR *** ELAPSED TIME = 6.562 TIME= 23:05:36
Target element 45977 belongs to rigid target surface, while an
underlying element was found. If intended to be a deformable pair,
ensure that each target element has full association (shares all the
nodes) with the underlying solid element.
I don't understand what is going on. This is for my grad project, and I just wante the finest simulation as I can get.
I asked and AI and suggested me to supress the contacts that generates the error. I did and it created another error. Then suggested me to change the configuration of those contacts:
Formulation: MPC
Behavior: Symmetric
It don't work. I'm getting frustrated. I just want to finish my project and get my engineer degree. I would appreciate any help in order to get my simulation running.
