    This usually happens if there are more than 1 part in the model and you did not Union all the parts that have ohmic connections.

    Or it could happen when you import a mesh and the mesh connectivity is poor.

     

    Open the OUT file in POSTFEKO. It will show the element numbers causing the error. On the Mesh tab you can find the elements in the 3D view.

    Then you will have to fix the mesh in those areas in CADFEKO, or in the external application if you imported the mesh from elsewhere.

    The *.out file will show something as follows:

     

    Intersection found between Triangle 316 and Triangle 442562
       Triangle         x                     y                       z

                          3.2470E-03  3.2449E+00 -1.2687E-01
    Intersecting elements found. Review the mesh connectivity in CADFEKO and correct the CAD model or merge coincident vertices for mesh models. Incorrectly detected intersections might also be caused by model extents that are set too large or by the maximum identical distance that is set incorrectly for the mesh.
     ERROR   40619: Intersecting elements found

     

    In POSTFEKO view the elements as follows:

    The following two videos about meshing and mesh fixing in CADFEKO would also help, here and here.

    Calculate the input impedance and radiation pattern of a dielectric resonator antenna (DRA) with a coaxial pin feed on a finite ground

    how  to calculate as theoritcally can i get any advices sir...
