+## Problem description
+
+This example is based on the The TASK D_THM1 of the DECOVALEX-THMC project.
+The TASK D_THM1 of the DECOVALEX-THMC project studies the coupled thermal hydraulic
+ and mechanical (THM) processes in the FEBEX type nuclear waster repository.
+ In the FEBEX type repository, nuclear waster canisters are stored in the
+ drifts excavated in the deep rock mass of granite, which is fully water
+ saturated, and they are sealed with bentonite. Initiallly, the betonite,
+ the sealing material, is partially saturated. TASK D_THM1 defines a 2D model
+ about the FEBEX type repository \cite BirEtAl:2008. In this example,
+ TASK D_THM1 is simplified in order to test the staggered scheme for TH process
+ in ogs6. The simplifications are
+<ol>
+<li><p>resizing the domain to an area that can represent the near field of an
+ installed nuclear water canister,</p></li>
+<li><p>assuming the the betonite is fully saturated from the beginning,</p></li>
+<li><p>ignoring the mechanical process.</p></li>
+</ol>
+<p>With such simplifications, the geometry of the present example is illustrated
+ in the following figure:</p>
+{{< img src="../decovalex_TH_domain.png" >}}
+<p>In the above figure, the domain in the annulus sector represents the sealing
+ material, bentonite. A heat power, which is generated by the nuclear waste with
+ one million year variation, is applied onto the inner arc of the annulus
+ sector. On the top boundary, the boundary conditions are
+ <span class="math inline"><em>p</em> = 4.3 ⋅ 10<sup>6</sup></span> Pa,
+ <span class="math inline"><em>T</em> = 294</span> K.
+ While on the bottom boundary, the boundary conditions are set as
+ <span class="math inline"><em>p</em> = 4.7 ⋅ 10<sup>6</sup></span> Pa,
+ <span class="math inline"><em>T</em> = 310</span> K.
+ The initial conditions are given as
+ <span class="math inline"><em>p</em> = 4.7 ⋅ 10<sup>6</sup></span> Pa,
+ <span class="math inline"><em>T</em> = 298</span> K.</p>
