Can anyone tell me if there exist analytical solution to the Fourier heat equation rhoCdt/dt= ∇.(k∇T) + S Thanks

Hi jfgobin ρ(t,r) is just the continuti equation from Maxwell's. I am solving this equation with matlab, and i am using pdepe solver. at the beginning if i assume my problem is in steady state then i can make ∂ρ/∂t zero. But the problem is i can't make "C"( coefficient of the time dependent...

Hi jfgobin the space charge distribution ρ(t,r) is unknown.

Hello I am solving DC conduction equation in Matlab. My equation is 1/r * ∂/∂r [r*σ* ∂V/∂r]=∂ρ/∂t My equation is 1D(only varies with radius) and time dependent. i am using pdepe solver.The space charge ( ρ) is the time dependent variable. But the form of MATLAB pdepe solver the time...

hello i am solving heat equation in cylindrical coordinator. i am using MATLAB "pdepe" solver to solve the partial differential equation. can anyone suggest me how to choose the initial condition?
