Is the characteristic admittance of a structure calculated using the fields tangential to the wave or to the port?

I am modelling a microwave structure using circuit theory, but I have a small confusion regarding characteristic admittances (I am assuming rotational symmetry and TM modes so I only have E_z, E_r...

Does anyone have tips regarding an algorithm for creating a mesh in 2D or in 3D?

I am beginning to work with 2D finite element analysis, and I am following Jin's book on FEM applied to electromagnetism. I already passed chapter 3, which deals with 1D problems and everything...

Is it possible to obtain EM fields in a resonator based on its Y or S matrices?

Circuital analysis is a technique that allows the separation of complex problems into simpler ones, which are then joined back into a single response. This way, the parameters of any structure...

Random generated problems

I have heard that a good way of testing a metaheuristic is by using random generated problems, but I am not sure if these can be considered as standard test functions with random parameters. If...

fatal error

When I tried to energy minimization my system, I got fatal error as below. Fatal error: Atomtype opls_116 not found Although I've already added this line: ; include water #include "oplsaa.ff/spc.itp" to [molecultype] directive in my topology.

Resistor definition in Piezoelectric bimorph with ANSYS workbench

Hello, good day! I am trying to simulate similar bimorph piezoelectric harvester with below commands. However, the output power doesn't change with resistor value. Please help to find the reason. ET,10,CIRCU94,0 !SET UP RESISTOR R,1,100000 !RESISTANCE VALUE TYPE,10 !SET ELEMENT TYPE E,1,2 !CREATE RESISTOR BETWEEN NODES 1 AND 2 Thanks in advance Regards,

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...

What is the characteristic length to determine the Reynolds number for the scattered turbulent fluid flow?

Dear all, I just saw this example in FB on the difference between laminar flow and turbulent flow. The flow from a pipe hits the sink and scattered. The flow from the pipe is characterized as...
