    Mesh Connectivity Problem

    Kumar Dandapani

      Hi Friends,

       

      I am getting Mesh connectivity Problem in my assembly between two parts.

      Why i am getting like this mesh connectivity problem. How to fix this problem. I tried with Adjusting mesh element size , Tolerance and Jacobin points. Even tried with High and Draft Quality mesh. I didn't get solution. If some one knows solution or Workaround Kindly let me know. Solidworks 2013 and 2014 also used to Fix. But not Fix the Problem. Thanks in Advance.

          This must have something to do with the Global contact condition.

           

          1) Set the Global contact to bonded with compatible mesh.

          2) If you have any Rigid bodies, automatically the Bonded contact becomes incompatible. You have to make the all the bodies deformable and make sure the global contact is bonded with compatible mesh.

           

          See if this helps.

              Hi Duarte,

               

              Thanks for your reply. But i tried what every you said. I used to given only Bonded contact on Global Contact and There is no Rigid Part also. You can review my Screen Shot of mesh,its shows some place only no mesh connectivity some place has mesh connectivity. So what every you said i tried. Thanks for your reply.

                  Have you checked if the option of remeshing the failed parts with incompatible mesh is on?

                  Maybe that part fails to mesh, and the software is automatically meshing that part  with incompatible mesh without asking it.

                   

                  And are the faces pointing at us in the picture coincident, or are they a little bit out of plane with each other? If there is a small distance between them, this could cause the mesh to seem incompatible if the zoom is far.

                      Hi Duarte,

                       

                      Thanks for your kind reply, I checked with failed parts mesh with incompatible mesh option that too not activated. We are trying to mesh with compatible mesh only. Parts not separated with some distance. Its touching each other and defined No penetration contact between the faces.

                      I tried with mesh control for part level, faces and edges also. not getting connectivity. Might be its takes automatically incompatible mesh for some region ha?

                      but in the same surface i am getting connectivity between nodes na.. why this happening?...Thanks

                  Kumar,

                  It would appear as if you are meshing the parts separately.  First thing I'd try is deleting all the mesh, apply a contact surface w/ no penetration between the two parts and select that edge or, better yet, the surface between them to apply mesh constraints to get the refinement you require.  Then mesh all parts at once.  The FEA will 'run' with incompatible mesh but it's not as good IMHO.

                      Hi James,

                      Thanks for your kind reply and i tried with what you said deleting mesh in the assembly. then i started meshing with defining no penetration contact between two parts. even it mesh like what i posted screen. I tried with mesh control for part level, faces and edges also. not getting connectivity. Might be its takes automatically incompatible mesh for some region ha?

                      but in the same surface i am getting connectivity between nodes na.. why this happening?...
