Exporting and importing data

In this section we cover the usage of exporters/importers in order to save/load data, such as the solution of the linear system arising from the finite element discretization of a differential problem, to/from an external file. The saved file can then be opened with a postprocessing software such as Paraview. LifeV supports three different file formats: HDF5, VTK and Ensight, the first one being by far the most used. In the following subsections, we describe the export and import procedures.

1. Exporting data - In this tutorial we save a finite element vector to an external file
2. Importing data - In this tutorial we load a finite element vector from an external file
