Introduction to the use of LifeV

This document is meant as a user guide as it describes how to use LifeV to approximate the solution PDEs by the Finite Element method.

The simulation workflow

Writing and reading a datafile - In this section the user can learn (i) how to write an input datafile for LifeV and (ii) how LifeV can parse it.

Mesh handling - In this section the user can learn (i) some basics on how to generate a mesh for LifeV using the open-source software Gmsh, (ii) how to read it in LifeV and (iii) how to partition it for parallel computations.

Assembling - In this section the user can learn (i) how to create the Finite Element Spaces, (ii) how to assemble the linear system and (iii) some basic facts regarding the management of the degrees of freedom.

Boundary conditions - In this section the user can learn (i) how to specify a boundary condition, (ii) how to apply the boundary conditions;

Linear solver - In this section the user can learn (i) how to solve the linear system arising from the finite elements discretization by setting different preconditioner types.

Exporting and importing data - In this section the user can learn how to export (import) finite element vectors and save (load) them to (from) an external file.
