Could anyone check this convergence problem in solver for the coupling of two single turn coils in comsol !??

I was trying to model the coupling of two single turn coils in Comsol 5.0 in 3D. this is same as the model in 2D presented in the model library of comsol which is named mutual-inductance. if you...

How can I calculate a volume integration of magnetic field including a divergence operator in Comsol derived values?

Hello, I modeled an eddy current coil scanning over a conductor, I have access to magnetic flux density (B) and electric field of coil (E) through the derived values and global evalyation in the...

Can anyone take a look at these two models for eddy current nondestructive testing in comsol?

I created a model for a coil located over a conductor, coil is a multiturn coil with driving current of 1 amper. I modeled the half of geometry and the quarter of geometry. By decreasing the...

Has anybody used the MOVING MESH or DEFORMED MESH for a 3D model in COMSOL?

Several times I tried to use these options to generate a movement for an eddy current simple circular coil (solenoid) in comsol and every time I failed to proceed. I was supposed to apply the...

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.

Arena simulation - how do i model the following model in ARENA (see description) (new to ARENA)?

Hello, I'm fairly new to ARENA and I have the following problem: I have two queues in which, in each queue, a different order type arrives (both having an arrival rate of exponential 10). Order...

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...

How to define and get results (stresses) for certain points of a model in abaqus, using python? When the size of the model changes?

I want to do a parameter study of a aixsymmetric cylinder in Abaqus. I want to create several jobs where I get the stresses for 3 different points in my model. These points are defined. I wrote a...
