Hi , My probe radius is 5mm in my model, I tried using Fine /standard meshing option in my model, but for both cases, there is the same error msg "The ratio of probe radius to length is very large" . My model is attached here. Kindly check the model and

    Hello,

    Feko's wire segment mesh is based on the thin wire approximation. Therefore, the wire segment's radius should be smaller than the segment's length (Maybe 5~10 times smaller).

    Please change the wire segment radius (5 → 0.001) in Modify mesh setting as shown below.
