Implicit finite difference method python
Did you know?
The error in a method's solution is defined as the difference between the approximation and the exact analytical solution. The two sources of error in finite difference methods are round-off error, the loss of precision due to computer rounding of decimal quantities, and truncation error or discretization error, the difference between the exact solution of the original differential equa… Witryna17 sty 2024 · This code solves for the steady-state heat transport in a 2D model of a microprocessor, ceramic casing and an aluminium heatsink. It uses either Jacobi or Gauss-Seidel relaxation method on a finite difference grid. It can be run with the microprocessor only, microprocessor and casing, or microprocessor with casing and …
