If your project contains an array of line objects, you can also define an array of '''Lumped Sources''' to be placed on those lines. If you insert a new lumped source, all line array objects, if any, will be listed in the Lumped Source dialog as eligible objects for lumped source placement. A lumped source will be placed on each element of the array. All the lumped sources will have identical direction and offset. However, you can prescribe certain amplitude and/or phase distribution among the array elements. The available '''Weight Distributions''' include '''Uniform''', '''Binomial''', '''Chebyshev''' and '''Data File'''. In the last case, you need to set a value for maximum side lobe level ('''SLL''') in dB. You can also define a '''Phase Progression''' in degrees along each of the three principal axes.

Just like lumped sources, you can place '''Lumped Loads''' on array of line objects. These loads can be resistors, capacitors, inductors or nonlinear diodes. If you insert a new lumped load, all line array objects, if any, will be listed in the Lumped Load dialog as eligible objects for lumped load placement. A lumped load will be placed on each element of the array. All the lumped load will have identical type, direction, offset and parameter values.

Analysis is the simplest and most straightforward simulation mode of the [[FDTD Module]]. It runs the FDTD time marching loop once. At the end of the simulation, the time-domain field data are transformed into the frequency domain using a discrete Fourier transform (DFT). As a result, you can generate wideband frequency data from a single time-domain simulation run. The other simulation modes will be explained later in this manual.
