Magnetostatics experiment flowchart - How can I improve this

[john kly]

Homework Statement

I'm attempting to write a FORTRAN program that calcuates the magnetic field, B, at any point outside of a bar magnet. I will be using a simple first order euler scheme for numerical surface integration.

Homework Equations

Here is the exact method I will be using: http://prntscr.com/icuqtj (image inserter wasn't working)

It seems like you are trying to implement a numerical surface integration method to calculate the magnetic field outside of a bar magnet using FORTRAN. This is a complex task and I commend you for taking it on. I would like to offer some suggestions and advice to help you in your endeavor.

Firstly, it is important to have a clear understanding of the equations and methods you are using before attempting to translate them into a programming language. I would recommend thoroughly studying the method you have provided and understanding each step and its purpose.

Once you have a clear understanding of the method, you can start breaking it down into smaller, more manageable steps. This will help you in creating a more organized and efficient flowchart. For example, you can start with the basic steps of setting up the problem, defining variables, and initializing values.

Next, you can move on to the steps involved in the numerical surface integration method, such as calculating the surface elements and their corresponding magnetic field contributions. Make sure to include any necessary loops and conditions in your flowchart to account for different scenarios.

It may also be helpful to consult with other programmers or scientists who have experience in FORTRAN or numerical methods. They may be able to offer valuable insights and advice on how to approach this problem.

Lastly, I would suggest testing your program with simple inputs and comparing the results to known solutions to ensure its accuracy. This will also help you identify any errors or areas that need improvement in your flowchart.

I hope this helps you in creating a more efficient and accurate flowchart for your FORTRAN program. Good luck with your project!
