I am interested to develop this numerical model, but i don't know how to start it ?

Hi guys i would like to develop this numerical model ?

The simulation program in MATLAB to calculate the magnetic field using the finite element software

[Jan]

The question is too general to be answered.

[Emma Stewart]

Calculate the magnetic field by using differential equation and forces ? is it possible?

[Emma Stewart]

Jan can you please mention your email address to provide the more details on the model, thank you

[Walter Roberson]

Looking at the material you sent me in email, I would think it very likely that Jan does not want to provide you with an email address to receive the details, and would instead far prefer that you posted the information here.

[Emma Stewart]

@Jan, I think Walter said it rightly. Here is the details about the model

This numerical simulation model written in MATLAB should consist below features

1) Calculation of the magnetic field using the finite element software

2) Material trajectory calculation by the Cromer method

3) calculation of the coordinates at the point of impact of the particles with the wall of the rotating cylindrical electrode,

4) calculation of the position and velocity of the particle after the impact, and

5) graphical representation of the results

This is just general details You can modify this features as well. Thanks a lot

Answer 1

Start with defining your goal. How should the result look like? Is it enough to write some scripts without documentation, which produce some diagrams, or should it have a professional level, because you want to sell the solution or submit it as PhD thesis?

Do you have the needed Matlab skills to implement this according to the defined goal? If not, start with Matlab's Onramp tutorial and some smaller projects.

You find a large variety of different "finite element software" methods. E.g. the grid can be fixed or adaptive, the code can be easy to read or highly optimized, etc. "The software" might mean, that you write the calculator by your own, or that your Matlab code creates the initial values only to create files used as inputs for professional programs.

"Magnetic field" can include relativistic effects e.g. for calculating the electro-magnetic fields on the surface of a magnetar. Maybe quantum fields matter, if you simulate the near-field of oscillating Cooper pairs in superconductors. Or it is a simple macorscopic simulation.

"calculation of the coordinates at the point of impact of the particles with the wall of the rotating cylindrical electrode" - It is really hard to follow you. On one hand you give far too few details to understand, what you want to do, and on the other hand some points contain too many details.

A "graphical representation" can be a real-time 3D-animation during the simulation, a post processed 3D animation, a set of 2D diagrams of the coordinates, or a bar graphic of the statistical distribution of some events.

So your point to start from is the decision, what you want to achieve. There is a large field of different approachs, which match the given keywords.

Currently your seem to be in the state of defining, which problem you want to solve. Then there is not relation to Matlab yet, because this phase is solved best with pencil, paper and coffee.

An excellent answer.
