Awesome video! I was looking for a more general version with a source function g.

Good video! Can you make a video of this problem with a second and third order boundary condition in spherical coordinates? It would be an interesting approach for the heat conduction

nice. how can I implement the same problem but on one end with neumann B.C dt/dx=0 at x=o

Please help me sir I don't understand how to change the program, for example, the initial temperature of the rod is 25oC I'm working on my final project and need to know about it Thank you

Hey, did you get how to do it?
@TheTechHans Жыл бұрын
In the matlab script the Array T is the temperature at nodes. T[0] is temperature at zeroth node... Initially temperature at all nodes is zero except at end nodes., Where it is 100. As time progresses the T is updated. For giving 25 deg as initial condition put T[2:end-1]=25 The above line should be added after the line, "T=zeros(1,nx) ;" in the script. ;

That's a nice video Where we use the 1D diffusion eq on it application or for what purpose?
@praveenkumarch45662 жыл бұрын
This equation models the physical phenomenon of diffusion, I mean spreading of a particular parameter (dependent variable) from higher concentration zones to lower concentration zone. Here I took an example of heat Diffusion,the parameter is temperature. We can also model diffusion of ink in water, then the parameter will be concentration of ink.

How to solve the equation if it contains the source term as well?

thanks ever so much it was nice script. but does it work for this du/dt=k, d2u/dx2 u(x,t=0)=h(1-(x/l)square) u(x-l)-u(x=-l)-0
@TheTechHans3 жыл бұрын
Thank you. This equation is a generalized 1D diffusion equation: (du/dt)=k* (d2u/dx2) Heat equation is also a Diffusion equation. So you can use the same Numerical Strategy as explained in this video. You need to modify the Matlab Script so that the initial conditions, Coefficient - "k" , and the end conditions are implemented as per the given data.
