Dear all, Is there any people research on the electromagnetic simulation by meshless or meshfree method? I am trying to study this method, could anyone discuss the advantages of this method, comparing to the traditional methods (fem, MOM, BEM, FDTD, and so on), the classical articles and books about this, and any free source code to help me to s
Hi all Does anybody have a matlab fem code for Laplace equation in a hexagon OR semicircle?
Hi, I want model a simple transmission line using fem and i want to write a code in MATLAB. so can any one tell me a good reference of modelling equations. I have coded 1D FDTD for a transmission line modelling using the book "Computational Electromagnetics" by David B. Davidson but For 1D fem case this refence doesnot (...)
while i was reading the topic i want to ask now when i use a software such as NEC OR HFSS or matlab or pascad it says that NEC uses MOM while HFSS uses fem; what kind of method did you use in matlab : so what is MOM,fem CAN İ HAVE SOME DETAİLS ABOUT İT :? THANKS ALOT AND What about the
A full vector fem is a good method for simulation of photonic crystal fibers.
Hi! HFSS is also based on fem. I believe COMSOL (femLAB) is a general physics program to solve differential equations. It's strength are that you can adapt the program to your special problem requirement. On the downside the code will not perform as well as specialized tools. Tools like HFSS and CST are specialized on (...)
Hi I think the book of vlakis, fem for electromagnetics, (you will find it in the EDA books upload download) is very good concerning your problem, it has several matlab scripts and comprehensive theory BR Adel_48
Try to write a .dll file: under LabVIEW this method allow to intarface the National's software with Matlab and C, C++ programs. So, look how You can manipulate .dll files under femLAB.
I'm trying to do a comparison between numerical solution based on MoM (NEC2 code, program SuperNEC) and fem-Finite Element Method (Ansoft's HFSS) versus theoretical solution of the same electromagnetical problem. To be more specific, I'm simulating a half-wave dipole in two cases: firstly the dipole has finite thickness (10000 > length/radius of
HFSS is memory consuming and therefore time consuming because is a fem code. Regards
I'm successful complile EMAP5 for win32. It's very interesting code for EM developes, because it's hybrid fem/MoM tool. Basics sode is writen in ANSI C so can be compiled for all platforms(UNIX, WIN, 32bit, 64bit). Now all function are OK :D For far field try example3. If anybody know some friend who programing GUI :P , it's should be
Hi dule ! It's normal that you need long time for solving in CST( based on fem code ). Without several processors and lot of memory you can not simulate and optimize so big structures in CST . For structures like combline filter try with specialized software like as WASP-NET ( ).
