Hi...

I meshed Plate with hole in 2D Ruled option, the mesh flow is fine but the problem is mesh are not connected with each other. Can any one solve the problem. If elements are not connected with each other any problem will arise during analysis?

    Maybe you need do 'equivalent' of nodes?

    Hi Nguyen-Dai.

    Its equivalent in all sides. If you see in naked eye you feel its well connected if i try to delete the elements by using connected elements its selecting only one portion of the elements. This problem is coming if i use ruled mesh option if i do automesh this problem is not there, I attached the photo for reference just check that once again.

    Hello,

     

    Normally, the connection should be mapped correctly with 'shared' edges (green lines, mixed visualization) at geometry level. See first picture.

    If you are using the automesher, then all lines are shared and you will see only one density value / shared edge.

    If you are meshing the surfaces step by step they will be also connected.

    See picture 2.

    You can check the connection by: Tools->edges->Find edges and correct it by equivalence, if there are nodes not connected.

    See picture 3:
