I'm working on a magnetic gear + generator model, for my final graduation project and, to prove the gear ratio of the magnetic gear, I will need to measure the flux density through a point of the airgap and perform a fast Fourier transform (FFT) to analyse it's spectrum and then prove the gear ratio.
Is there any way that I can do that?
If you guys know a way, PLEASE let me know!!
You can e-mail me to krugercassio@gmail.com
Also, you can see my model at github: https://github.com/CassioKruger/PDD1

I'm working on some electrical machines (generators) models and I'm needing to use a variating speed at the rotor based on the actual time of the simulation. My idea is to use a velocity input that looks like a wind variation speed in order to use a frequency inverter to guarantee the 60hz output.
Is there any way that I can use a variating speed at the rotor, not a constant value?

I hope this is the correct place to post a question like that.
I’ve been working in a combined 1D and 2D finite element (FE) model in GetDP with a magnetic field (H) formulation and I’d like to connect the intensity of magnetic field over an edge in 2D with the boundary of a 1D FE system (see figure below). For this purpose, I’ve created two independent “FunctionSpaces” and I tried to apply a constraint of type “Link” to connect the related Degrees of Freedom. However, as each edge in the 2D system is defined by two nodes, the elements in the 2D and 1D regions are not geometrically identical (edges in 2D and nodes in 1D) and I couldn’t apply this type of constraint directly.
![Link2](/uploads/8bad1305cb113bf73c78c7abea7d8360/Link2.jpg)
Thus, I was wondering if there is any way to connect them using a constraint “Link”. Maybe with the optional “FunctionRef” function, but I couldn’t figure out how it works. If possible, could you please give me an example of the application of the “Link” with “FunctionRef”?
Thank you and best regards,

I've been work on a magnetic gear project (https://github.com/CassioKruger/PDD-pure) and I'm having trouble to compute the velocity of the moving bands. I took the "machine_magstadyn_a.pro" file to base my project and added some modifications to use it with 2 rotors instead of 1.
There is a gear ratio between both rotors, so I made this in my .pro file:
```
// pdd gear ratio:
// pH*wH + pL*wL = nP*wP
// wH is the speed of the inner rotor
// wL is the speed of the outer rotor
// wP is the speed of the modulators
// When one of the three parts of the gear is stationary, there will be a constant relation or gear ratio
// between the speeds of other two parts.
// considering that the outer rotor is stationary, the gear ratio becomes:
// -> pH*wH = nP*wP
// -> Gr = pH/nP = wP/wH
// -> gear ratio = nbr of poles at rotor 1 / nbr of modulators
// in this case, the nbr of modulators is equal to the nbr of poles at the outer rotor, so:
gear_ratio = NbrPolesInModel/NbrSectStatorMag;
delta_theta[] = delta_theta_deg * deg2rad ; //rotor 1 step
delta_theta2[] = delta_theta[] * gear_ratio ; //rotor 2 step
```
those "delta_theta[]" should be the step of each rotor to use with "ChangeOfCoordinates" inside the timeloop of the "machine_magstadyn_a_2rotors.pro" file, like this:
```
ChangeOfCoordinates[ NodesOf[Rotor_Moving], RotatePZ[delta_theta[]]];
ChangeOfCoordinates[ NodesOf[Rotor2_Moving], RotatePZ[delta_theta2[]]];
```
and that's working nice, the gear ration is clearly seen at the simulation. But the thing that I'm couldn't figure out is how to compute the correct speed and position of each rotor, so I can show it with graphs and prove that my model is working. I've made this:
-First, I've declared a "DomainKin2", because now there is 2 parts moving
-Then, inside the "Constraint{}" I made this:
```
Constraint{
...
...
...
//Kinetics
{ Name CurrentPosition ; // [m]
Case {
{ Region DomainKin ; Type Init ; Value ($PreviousPosition = 0) ; }
}
}
{ Name CurrentVelocity ; // [rad/s]
Case {
{ Region DomainKin ; Type Init ; Value ($PreviousVelocity = 0) ; }
}
}
//Kinetics - MOVING BAND 2

}
}

Thanks in advance!!!https://gitlab.onelab.info/getdp/getdp/-/issues/49Transient Heat Transfer Problem2018-11-04T21:10:35ZAsimTransient Heat Transfer ProblemHello Everyone,
I am trying to model a transient heat transfer problem (Wellbore within multiple Reservoir Domains of variable properties). I have generated the geometry file and defined the problem. But having some error while running those files (named Cylindrical); like undefined sub-region Reservoir_ID2.
In another case (named Cylindrical 2), I just defined only one reservoir region to overcome this error and it worked. But when I am trying to execute these files, I am getting an error; Not piece-wise Expression: k. for the line where I am defining the thermal conductivity k of my reservoir domain.
I am also trying to generate a GNU plot but it is not generating any file for that and it is only generating the Temp. Map file T.pos.
Can you kindly look into those files and help me resolve these errors. I am a student and a new user of getdp, and doesn't have any coding back-ground, I will appreciate if you can modify the attached files with the resolution of the problem and send them back to me so I can run them.
Best Regards,
Asim Hussain

[Cylindrical2.pro](/uploads/8aea9125042b5ccb3120f78c464cfd04/Cylindrical2.pro)Hello Everyone,
I am trying to model a transient heat transfer problem (Wellbore within multiple Reservoir Domains of variable properties). I have generated the geometry file and defined the problem. But having some error while running those files (named Cylindrical); like undefined sub-region Reservoir_ID2.
In another case (named Cylindrical 2), I just defined only one reservoir region to overcome this error and it worked. But when I am trying to execute these files, I am getting an error; Not piece-wise Expression: k. for the line where I am defining the thermal conductivity k of my reservoir domain.
I am also trying to generate a GNU plot but it is not generating any file for that and it is only generating the Temp. Map file T.pos.
Can you kindly look into those files and help me resolve these errors. I am a student and a new user of getdp, and doesn't have any coding back-ground, I will appreciate if you can modify the attached files with the resolution of the problem and send them back to me so I can run them.
Best Regards,
Asim Hussain

It seems to work for linear elements but when activating the second order option/flag, the results near the Dirichlet boundary with inhomogeneous data are wrong. I attached the updated wrench2D.pro as well as screen shots of the results with linear / second order. Are further changes required to deal with inhomogeneous data?

I am trying to use your "Inductor" model for obtaining the inductance in Time Domain simulation.
First, in the formula to calculate the inductance you should substitute the term "II" with the actual value of the current "$I"
to obtain the good result.
However, the simulation gives wrong results (in 2D and 3D) simulating the system with a conducting core.
The inductance in function of time should be constant, and should be lower with a conducting core because eddy currents creates
an opposite flux that make the total flux (then the inductance L=Psi/I) decrease.
Do you know what can be the cause of it ?
Thanks in advance,

https://gitlab.onelab.info/getdp/getdp/-/issues/37magnetostatics simulation gives wrong results2017-08-05T11:56:16ZChristophe Geuzainemagnetostatics simulation gives wrong resultsI made a model with one magnet and an iron frame (mu_r = 9000) wrapped around it. I expect most of the B lines should go inside the iron frame, but the simulation result seems as if the iron frame does not exist. Please see attached from the geo model. Open the geo model in gmsh first, then merge (gmsh menu: File >> Merge) in magnetostatics.pro in the template folder came with gmsh. You should be able to set the model interactively. Set a constant magnetization for the magnet of 900000 in z direction. Select the right materials for air, set frame with constant mu_r = 9000, and the boundary condition on "Inf" can be either way (may leave at its default value). Then click Run.
