Advantage of FDM:

  1. This method is highly accurate, since it uses fine mesh.
  2. It is the only widely used method in time domain for solving general problems.
  3. Simple to implement than MOM or FEM.

Disadvantage of FDM:

  1. Meshing is inflexible
  2. Uncertainty about precision of boundaries
  3. Frequency domain finite difference formulation are available but never become popular for general problems.
