There are many considerations to take into account when assessing the suitability of a particular EM analysis tool for design. Although in principal these two technologies could be used to solve the same problems there are often good practical reasons why one particular simulator is better suited to solving a particular problem type. Choosing the right technique for solving a design problem is important, as choosing the wrong one can either result in incorrect results, or results which take excessively long to compute.įinite Element (FEM) and Finite Difference Time Domain (FDTD) solutions are used almost in all commercial software. Solver for a particular design can be selected based on type and size of the design.
There are various EM simulation tools based on different numerical techniques. The answer to this question depends on to a great extent on the particular design problem that is to be analyzed.
