* In the Lumped Element Properties Section, you can set the type of the load. In the dropdown list you have four options: '''Resistor''', '''Inductor''', '''Capacitor''' and '''Diode'''. The resistance is expressed in Ohms (O), inductance in Nano-Henry (nH) and capacitance in Pico-Farad (pF). In the case of a diode, you have to specify the '''Saturation Current''' in femto-Ampere (fA), the ambient '''Temperature''' in Degree Kelvin and also the diode's '''Ideality Factor''', which is usually a number between 1 and 2.
<font color="red"><u>'''NOTE: {{Note|Small values of inductance may result in the divergence of the FDTD numerical scheme. To avoid this problem, you need to increase the mesh resolution and adopt a higher mesh density. This, of course, may lead to a much longer computation time.'''</u></font>}}
