Numerical Solution for Bessel Equation

Hello folks, I'm trying to solve the Bessel equation that arises from the heat transfer equation of a straight triangulat fin. I know the analytical solution, but need to calculate the numerical...

Re: Numerical Solution for Bessel Equation

Hi Valery, I had tried it before but was not getting anywhere. I finally was able to find the problem: dT/dx =0 @ 0 does not converge so instead had to change the left boundary of the domain to .000001...

Re: Numerical Solution for Bessel Equation

Sometime I use not the built-in but user rkfixed function: I can see a part of solution

Re: Numerical Solution for Bessel Equation

Thanks, Josue,It is a good example for the new edition of this book - a solution is nothing, a way to solution is...

Re: Numerical Solution for Bessel Equation

Hi Valery, Thanks for sharing your program for a user-defined alternative to rkfixed. What actually makes this problem interesting is the boundary condition definition at the fin tip.  From the...
