HFSS and CST are highly specialized EM-Solver. I believe that the specialized solvers are more effective. Most EM design use specialized tools and not general purpose DE-Solvers. However, in tools like COMSOL you might have more flexibility if you have some coupled mechanical/thermal/electric problems.electromagnetic wave propagation and resonance effects in high-frequency applications. Simulations of this kind result in more powerful and efficient products ... All these steps are accessed from the COMSOL Desktop. The solver step is usually carried out automatically using default settings, which are tuned for each specific RF interface.using the default eigenvalue solver available in COMSOL. 0 2(𝜖 𝑟− 𝜎 𝜔𝜖0)𝐄, (2) where 0 is the wave number, ω is the angular eigenfrequency, =√−1, and σ is the electrical conductivity. The electric field vector of the π-mode is plotted in Fig. 5 (arrow). In order to get a wellThose applications can be deployed over the web using COMSOL Server, or compiled with COMSOL Compiler to run stand-alone. Model setup is quick, thanks to a number of predefined modeling interfaces for applications ranging from fluid flow and heat transfer to structural mechanics and electromagnetic analyses. 9 Forward Modeling of Geophysical Electromagnetic 10 Methods Using Comsol S.L.
