Solving Laplace's equation over a triangular domain.

Click For Summary
SUMMARY

This discussion focuses on solving Laplace's equation, specifically in the context of a triangular domain using finite difference methods. The equation in question is \nabla^2 \phi = 0, which simplifies to \frac{\partial^2\phi}{\partial x^2}+ \frac{\partial^2\phi}{\partial y^2}= 0 in two dimensions. The terms "M" and "N" refer to the number of mesh points used in the numerical method, which is crucial for accurate solutions. The conversation emphasizes the importance of understanding the problem context and the need for participants to demonstrate their current understanding for effective assistance.

When solving Laplace's equation over a triangular domain. Why is it a good idea to take M = N?
 
Physics news on Phys.org


I have no idea what you are talking about. Laplace's equation is
\nabla^2 \phi= 0
I assume, since you say "triangular domain" that this is in two dimensions:
\frac{\partial^2\phi}{\partial x^2}+ \frac{\partial^2\phi}{\partial y^2}= 0
but I have no idea what "M" and "N" are.

edit: from your next thread it appears you are talking about a finite difference numerical method and M and N are the number of mesh points. It would have helped if you had said that!

In any case, these both look like homework problems so I am going to move them there. Also, we need to know what you understand about these and where your difficulty is so you will need to show some work before we can help you.
