This tutorial is based on Lesson 2 - Loading a Domain. It shows how a discretization of the laplace problem can be set up and how an exact solver can be used to solve the problem. We will use script callbacks to specify the diffusion tensor and the right hand side as well as the dirichlet boundary values. The results are finally written to a .vtk file which can be opened with ParaView or similar software.

Below you'll find the scripts sources. They are the same as in apps/tutorials/tut03_laplace_with_exact_solver.lua.
