Witryna29 paź 2010 · Include the section of code that actually performs the finite difference, the number of points you calculate at (i.e. your mesh size) and how fast it runs vs how fast you think it could / would like it to – J Richard Snape May 31, 2015 at 8:31 Then, open another question or place a comment on this? – Riccardo De Nigris Jun 1, 2015 at 8:16 Witryna6 lut 2015 · Next we use the forward difference operator to estimate the first term in the diffusion equation: The second term is expressed using the estimation of the second order partial derivative: Now the diffusion equation can be written as. This is equivalent to: The expression is called the diffusion number, denoted here with s:

Python … WitrynaA popular method for discretizing the diffusion term in the heat equation is the Crank-Nicolson scheme. It is a second-order accurate implicit method that is defined for a generic equation y ′ = f ( y, t) as: y n + 1 − y n Δ t = 1 2 ( f ( y n + 1, t n + 1) + f ( y n, t n)).
