linear_elasticity/its2D_interactive.py
======================================

**Description**


Diametrically point loaded 2-D disk, using commands for interactive use. See
:ref:`sec-primer`.

The script combines the functionality of all the ``its2D_?.py`` examples and
allows setting various simulation parameters, namely:

- material parameters
- displacement field approximation order
- uniform mesh refinement level

The example shows also how to probe the results as in
:ref:`linear_elasticity-its2D_4`, and how to display the results using Mayavi.
Using :mod:`sfepy.discrete.probes` allows correct probing of fields with the
approximation order greater than one.

In the SfePy top-level directory the following command can be used to get usage
information::

  python examples/linear_elasticity/its2D_interactive.py -h

Notes
-----

The ``--probe`` and ``--show`` options work simultaneously only if Mayavi and
Matplotlib use the same backend type (for example wx).
