Thank you so much

Can you guide me about adaptive mesh method or send some links about it?

For my work i have a simple numerical solution. i need to generate a Gaussian pulse and then to propagate along the fiber length. i can use simple difference derivative or Crank Nicholson difference. The solution has the form: Ai+1,n = Ai,n +j delta x ( ½ β2(Ai,n+1 – 2Ai,n + Ai,n-1)/delta t2 )...

i don't understand the difference but yes i want time dependent solution

Sir can you email main that code? my email is syedmohsinshah@gmail.com If you give me some time i will discuss my work with you by email.

Hello, i am working on pulse propagation in optical fiber. i have to simulate the nonlinear Schrödinger equation using the FDTD (Finite Difference Time Domain) method. The Schrödinger equation has the form dA/dz = i/2 β2 d2A/dt2 –α/2 +iγ |A2|A where β2 is dispersion, α is...
