2_8 LaPlace and Poisson Equations

This video was made for a junior electromagnetics course in electrical engineering at Bucknell University, USA. The video is designed to be used as the out-of-the-classroom component and combined with active learning excercises in class. This video completes the "electrostatic triangle", introduces the LaPlace and Poisson Equations, and shows how to numerically solve LaPlace's equation given fixed boundary conditions.

Thank you very much for this video.

I am trying to simulate a fluid over a discretized grid and I had trouble understanding how a fluid moves in/out of a grid cell(whose behaviour is defined by the poisson equation) and also I had trouble understanding how iteratively solving linear equations helps us with computing a pressure field but this video solved both those questions.

Thank you very much indeed :)

Really nice lectures! Wish you would make some more Antenna videos though. Btw I have watched 4.1-4.3.

the equation that appears at 7:27, is there a typo in that V(x-dx, y)+V(x-dx, y)=...?  isn't it suppose to be V(x-dx, y)+V(x+dx, y)=...?  trying to program this. thanks

what about programming a solution in the software you mention ?? wheree could i find some examples ?
Nice job with the vid by the way

Question: Souldnt it be E= - grad(V) in the triangle fig. (at 0:30, arrow from right to left)?

MS Excel for mac 2011 allows iteration under "Preferences, Calculation." Accuracy increases if set to 10, 000 iterations max with maximum change, say Result also looks plausible if put a source in the grid by entering a constant instead of the formula, because delh squared in video is small.

I don’t understand a single fking sentence...but I feel smart just by listening to this.
