![]() ![]() By making the domains smaller the peak memory can also be lowered. Good news – with DDM solver the peak memory relates to the number and size of domains per core. CST 5G Phased Array Antenna Design and Beamforming using CST Simulation Master 1. If your structure contains geometrically identical elements – like antenna arrays – DDM solver allows setting up of repetitions. 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. 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. whatsapp no +923119882901If you want to design a project/need help/teach you email me Antenna/filter, power combiner/divider, coupler. 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.
