Importing meshes with IMAS
==========================

In this tutorial the presentation of an alternative way of mesh
preparation for the Inres1 test case (section :ref:`inres1-case`),
presented in :ref:`inres1-case-meshing`, using IMAS and its IDS
databases instead of manually importing and preparing the meshes. The
rest of the case procedure - calculation, results analysis etc. is the
same as in the :ref:`inres1-case`, continuing from the section
:ref:`inres1_case_preparation`.

For introduction to IMAS and IDS see HOWTO :ref:`imas`.


Downloading prepared IDS
""""""""""""""""""""""""

First, in order to import meshes using IMAS the required IDS database,
containing the required meshes, must be available.
For the purposes of this tutorial the IDS was prepared beforehand.

In order to download the IDS, run the following command from base
smiter directory:

.. code-block:: console

    $ make -C study/imas

This will download and extract multiple SMITER benchmark IDSs to
``~/public/imasdb/smiter/3/0``, including the one needed in this tutorial
(IDS with parameters shot: 6, run: 5).

Reading mesh from the IDS
"""""""""""""""""""""""""

1. To read the mesh from IDS, activate the SMITER module. Then proceed to
   run the IDS2SMESH tool, either by clicking on the |imas_read_ids| or
   click on :menuselection:`&Smiter -> &IMAS -> Read mesh from IDS` from
   the menu.

2. A popup window will display.

   .. image:: images/inres1_imas_IDS2SMESH_window.*
      :align: center

   Insert the following parameters of the IDS *get* dialogue:

    * run: 6
    * shot: 5
    * user: ${USER}
    * device: smiter

    where ${USER} is your system username.

3. Click :guilabel:`Apply`. If everything went ``OK``, a message will
   be displayed

   .. image:: images/inres1_imas_IDS2SMESH_finish.*
      :align: center

   Click :guilabel:`Ok` and afterwards :guilabel:`Close`.

New meshes will be shown in the ``SALOME Object browser`` with the meshes
representing:

   * smiter-aux -> Wall mesh
   * target -> Target mesh
   * shadow -> Shadow mesh

4. Activate ``Mesh`` module.

   .. image:: images/inres1_imas_mesh_module_select.*
      :align: center

5. Display the loaded meshes in the ``SMESH`` module. The display of each
mesh can be turned on/off by right clicking on the mesh in the ``SALOME Object
browser`` (multiple selection is possible) and selecting ``Show`` or by
clicking the eye icon on the left side of the mesh name.

Now the meshes are prepared and the the rest of the Inres1 case tutorial
(case computation preparation, run instructions, resulty analysis etc.)
can be followed in section :ref:`inres1_case_preparation`.
