Crank Nicolson Scheme for the Heat Equation

people.sc.fsu.edu

Crank Nicolson Scheme for the Heat Equation The goal of this section is to derive a 2-level scheme for the heat equation which has no stability requirement and is second order in both space and time. From our previous work we expect the scheme to be implicit. This scheme is called the Crank-Nicolson

We now revisit the transient heat equation, this time with sources/sinks, as an example for two-dimensional FD problem. In 2D (fx,zgspace), we can write rcp ¶T ¶t = ¶ ¶x kx ¶T ¶x + ¶ ¶z kz ¶T ¶z +Q (1) where, r is density, cp heat capacity, kx,z the thermal conductivities in x and z direction, and Q radiogenic heat production.
