Meshing to define contact elements
Meshing to define contact elements
(OP)
Hello,
I am trying to model a plain strain problem with 2 layers, one on top of another,the line of interface making 45 deg w.r.t sides.To visualize, try cutting a rectagle such that it appears to be formed by placing 2 trapeziums along the slant.
I want to define contact elemnts at interface.I use plane 182 and when i try to mesh, there appears a dense mesh along the interface! It would be easy for computation and allow me to couple DOF of certain contact elements if the meshing is not so dense. I get even meshing when i have one line at the interface but then, i am unable to generate contact elements. Is there a way to get the an even mesh and contact elements ?
Thanks.

I tried a circular inclusion at center of a square sometime back and even then i did not control the mesh density at line(arc). BUt still i got a neat mesh. While trying, i found that using auto shapes in ansys (triangle, square, rectangle,circle ,polygon) as inclusion in a square/rectangle background and automatic meshing gives a neat mesh at the line interface.
Thanks.
