I see the following warning:

Warning 274: A dielectric body does not have a closed surface.


What does it mean and what should I do to fix it?

    This warning is given when a dielectric solved with the surface equivalence principle (SEP) is not completely closed. The formulation of the SEP requires that the dielectric firstly does not contain any openings and secondly that the mesh of this dielectric contains no free edges (that is to say, all the triangle edges are joined properly together).

    If the above two requirements are not met, this warning will be given and results could be wrong.

    An easy way to see if these requirements are met is to check if a region is reported in the detail tree.

    In addition unconnected triangle edges can be displayed with 'Connectivity' in CADFEKO or POSTFEKO.
