1511This tutorial explains how to read a mesh metadata (data about the elements, nodes, faces, region, zone ...)
16- for LSDYNA, Fluent or CFX result files .
12+ before extracting the mesh from a result file .

18- The mesh object in DPF is a |MeshedRegion |. You can obtain a |MeshedRegion | by creating your
19- own by scratch or by getting it from a result file. For more information check the
20- :ref: `tutorials_create_a_mesh_from_scratch ` and :ref: `tutorials_get_mesh_from_result_file ` tutorials.

22- We have the | MeshInfo | object to read metadata information before extracting the | MeshedRegion |.
23- You can obtain this object by creating a | Model | with a result file.

28- Here we we will download result files available in our |Examples | package.
29- For more information about how to import your result file in DPF check
30- the :ref: `ref_tutorials_import_data ` tutorial section.
20+ First, import a result file. For this tutorial, you can use one available in the |Examples | module.
21+ For more information about how to import your own result file in DPF, see the :ref: `ref_tutorials_import_data `
22+ tutorial section.
