Eigen mode solver is not the right choice to study waveguide modes you want as Eigen mode solver takes every structure as cavity and calculates the resonant modes as this is from where this name Eigen comes from. I think for your purpose simulate your waveguide with frequency domain solver. I think that will (...)
Hi, I am facing problem in finding the input impedance of a unit cell FSS in CST with FSS unit cell template. BY applying unit cell boundary conditions and floquet ports and then simulating with frequency domain solver, I get the S parameters but the input impedance is not calculated. BY simulating simultaneously with floquet ports and (...)
Hi guys! I am here new like in a field of EM simulations. I started to use CST software for simulation microstrip patch antenna @ 5.8 GHz, feed with coaxial probe. I am interested which of the above mentioned solvers are better in sense of accuracy (which will give better matching with measured results of S11 parameter)? In addition if you have
hello friends i want to simulate 2 layer pcb and calculate s parameters. this 2 layer pcb have complex structure . in cst micro wave studio with frequency domain solver its have too long time for simulating and not appropriate . can any one help me to reduce thats needed time for simulation ? :cry::cry:
When I run frequency domain solver with hexahedral. Simulation stopped and Message showed Materials with magnetic dispersion or magnetic conductivity in port regions are not supported. What ddoes it mean? Thanks!
What is your mesh definition? As your frequency is very high so proper and dense mesh must be used to get accurate results.
Hello everyone, I am new to CST just few days back learned it to design and simulate the GPS antenna. The antenna which is already implemented in one of the IEEE paper but for my project work i am doing it. My antenna is "Stacked Patched" type with "Reactive Impedance Surface" on the most bottom substrate. I am using Coaxia
I was solving a very complex coil, there was always a problem saying error accessing 1D result storage. Then solver stops automatically. I do not understand why. Note there are no other errors, just some low quality elements in my meshing. I am using high frequency problem and frequency domain solver. Did (...)
Dear all, Can anyone show me that how to plot antenna gain vs. frequency when using CST frequency domain solver? When using CST time domain solver, I have plotted antenna gain vs. frequency based on broadband monitors. However, CST does not support broadband monitors (...)
Hello, What frequency are you operating at? For electrically large models, try using the I-solver. You could also try simulating the horn(if that is not too large) and monitor the fields around it (field source monitor).Then import the field source into a new simulation with the lens with it. That should save you some mesh in the models.
hi everybody. I am simulating an antenna in CST software with frequency domain solver. my frequency range is 0.7 GHz- 2.4 GHz. the result is good. my problem is step frequency. CST give me the result with step frequency of 0.002 GHz but i need to know what exactly is happening in each step (...)
Hey! I need help for EM Studio. I try to explain it with an easy example. I want set in Low frequency domain solver a current Port on the one side of a cylinder and then show the voltage in this cylinder. How i can set the Voltage Monitor? I find anywere this Option with Low frequency domain (...)
Hi Could anyone explain to me the concept and significance of mesh density as a function of steps per wavelength? I am asking this in context of a frequency domain EM-solver - CST MWS. May I ask what are the "steps" and what is the "wavelength" ? I am trying to simulate a Photonic Crystal (silicon pillars in vacuum) within a (...)
Greetings, I am trying to model for the first time, so I tried to simulate the standard model form the paper Robinson et al, Analytical formulation for shielding with apertures. To test the Electric fields with probes inside the shielding box I ran the frequency domain solver in CST MWS. How do I get finer results that match the (...)
Hi ! I am new to CSt MWS and I want to analyze a periodic structure, I use the unit cell as boundary conditions, so the software puts automatically Floquet ports. But the "Set excitation" line in the "QuickStart Guide" does not get checked. I then run the frequency domain solver and get results that are ok. The only way to get the (...)
Hi, tell me is it possible to calculate the RCS in the plane of the Phi=90 theta=0..180, not counting 3D RCS. 3D graph is not needed, needed only a polar graph. How to do this in order to facilitate the calculation? Used frequency domain solver. Sorry for my English.
Hi,how we can import cst microwave studio frequency domain solver results to matlab for plot curves?
i having some problem with my CST simulation of PIFA antenna. A simple two layer board simulation (frequency domain solver) requires me to use FPBA instead of automatic. when i use FPBA, its refining the mesh again and again untill the end but doesnt solve the problem. The weird thing i observed is the boundary condition (box) is too (...)
What is your transient solver? I think the periodic boundary condition are used in the frequency domain and commercial software can not solved structures with periodic boundary condition in the time domain.
Dear Eleazar_777 I executed your file with frequency domain solver in CST. I could not see any problem. I think your file is true. please check it and inform me. Tanx. HR Kar
