At this time, your project is ready for the Wire MoM simulation of your dipole antenna structure. For wire structures, [[EM.Libera]] generates a wireframe mesh. It automatically detects whether your physical structure requires a surface mesh or a wireframe mesh. Open the Mesh Settings Dialog and change the value of '''Mesh Density''' to 30 cells per wavelength.

Visualize the current distribution on the wire dipole. You can see the familiar sinusoidal current distribution on the wire with its peak at the center and zero current at the two ends.

Next, visualize the 3D radiation pattern of the dipole antenna. You will see the familiar donut shape with a directivity of 1.64.
