Loved this sir. I particularly appreciate your emphasis about the s number being less than or equal to 1 to achieve convergence in the solution. Otherwise, the solution blows up even if slightly less than one.

where you have applied BCs in numerical method, there two BCs required?

Hi Abolfazl,
I have just a question. You know if it is possible to use finite difference method to growth droplets for condensation in clouds ?
Best,

Hello, thank you for the video. I am trying to model 2D wave eqn, but i am having problem making/understanding PML. Can you help?

I have a question if we want to use matlab for 2D wave equation, and I want to build a 3d meshgrid like [T, X, Y], how can I do this??

Can you make a video where forcing term for vibration problem and source term in heat problem are there?

I have struggled so much with implementation of finite difference EQ. Thank you so much. I have a question, my code is producing delta t with a linspace of 0 to 30, not 0 to 300. Is my plot just not showing the factor of 10?

One more question if the source is not zero and I have only reflecting boundary conditions how can we do this?

Dear sir
You have done a great job. It looks really nice
Can you modify it for standing wave equation?

Thank you sir.I'm calculating ∂²u(x, t)/∂t² = c²∂²u(x, t)/∂x² + F(x, t) using the explicit finite difference method. Δt ≤ Δx / c has been satisfied, but the solution still has numerical oscillations.what is the possible reason？

Thank for the work, but we don't see the code
