Hello there. I am really new to all FEM method and i am trying to simulate a simple wire antenna consisting of a bended wire in a semiloop, with one end conected to the generator and the other end connected to a 50 ohm load. The solver fails as follows: Failed to find a solution for the initial parameter. Singular matrix.
There are 1 void equations (empty rows in matrix) for the variable comp1.emw.S2x. at coordinates: (0,0,0), ... and similarly for the degrees of freedom (empty columns in matrix). Returned solution is not converged.
Any ideas? Here is the file, https://dropfiles.org/AgX5LzD4

I haven't looked at your file, but I (and possibly many other people) will be happy to do so, if you save a version with the solution cleared (which will make the file much smaller) and then upload it to this forum.
