The seamless integration of the solvers into one user interface in CST Studio Suite enables the easy selection of the most appropriate simulation method for a given problem class, delivering improved simulation performance and unprecedented simulation reliability through cross-verification. Alongside these are simulation methods available for charged particle dynamics, electronics, and multiphysics problems. These represent the most powerful general purpose solvers for high frequency simulation tasks.Īdditional solvers for specialist high frequency applications such as electrically large or highly resonant structures complement the general purpose solvers.ĬST Studio Suite includes FEM solvers dedicated to static and low frequency applications such as electromechanical devices, transformers or sensors. By making the domains smaller the peak memory can also be lowered.CST Studio Suite® gives customers access to multiple electromagnetic (EM) simulation solvers which use methods such as the finite element method (FEM) the finite integration technique (FIT), and the transmission line matrix method (TLM). Good news – with DDM solver the peak memory relates to the number and size of domains per core. If your structure contains geometrically identical elements – like antenna arrays – DDM solver allows setting up of repetitions. Visualize & Extract Primary Results (S-Parameters, Nearfield distribution, Farfield) & more advanced Results using the Postprocessing (i.e. Direct Frequency Solver requires a big amount of RAM for managing big simulations, and sometimes you just do not have enough to work with.īy dividing the structure into smaller domains DDM solver gives a good simulation speedup, as domains can be solved in parallel, depending on the number of cores. Construct & Simulate Antennas using different solvers. On the contrary, simulation time with Frequency Domain Solver is independent of the number of ports in the structure. When the count goes on hundreds, it can result in days of simulation. It means that the more ports you have, the longer simulation time you get. Time Domain Solver calculates each port sequentially. Most mm-wave applications require dual-polarization, which multiplies the number of ports by 2, resulting in 32. It is a 4×4 array, that gives us 16 elements in total, or 16 ports. Let’s look at a simple cavity mm-wave antenna array, that works in the 24-32GHz range.
