|
||
|
||
<h3 id="61-create-boundary-surface">6.1 Create boundary surface</h3>
|
||
|
||
<p>We now have a mesh with complex stratigraphy encoded in its material ID.
|
||
However, the domain of this mesh is a rather boring cuboid and doesn’t
|
||
accurately reflect the geospatial domain that we are trying to model.</p>
|
||
|
||
<p>By importing a polyline, the exterior boundary of the mesh can be truncated.
|
||
As in previous steps, we will use a mesh to define a <code class="language-plaintext highlighter-rouge">region</code> that will be used
|
||
for element-wise operations.</p>
|
||
|
||
<p>However, the boundary is a line object. In order to use it as a surface/region,
|
||
it must be a surface. A polyline can be turned into a vertical surface by
|
||
‘extruding’ it in the vertical (0,0,1) direction:</p>
|
||
|
||
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>read / avs / basin_bnd_ply_rescale.inp / mo_bndry
|
||
extrude / mo_fence / mo_bndry / const / 3200. / volume / 0. 0. -1.
|
||
</code></pre></div></div>
|
||
|
||
<p>We will also translate the extrusion so that it covers the vertical extent
|
||
of the hex mesh:</p>
|
||
|
||
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>trans / 1 0 0 / 0. 0. -3200. / 0. 0. 0.
|
||
</code></pre></div></div>

||

||

<h3 id="62-truncate-mesh">6.2 Truncate mesh</h3>
|
||
|
||
<p>Next, we use the boundary to truncate (remove) cells outside the boundary.</p>
|
||
|
||
<p>There are three ways to define ‘outside’:</p>
|
||
|
||
<ol>
|
||
<li>Only remove a cell if ALL vertices are outside</li>
|
||
<li>Remove a cell if the centroid (average of all vertices) is outside</li>
|
||
<li>Remove a cell if one or more vertices are outside</li>
|
||
</ol>

<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>cmo / select / MONAME

</code></pre></div></div>
|

<p><strong>Method 1:</strong></p>
|

<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>eltset / e_delete1 / exclusive / pset get p_bndry

<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>eltset / e_delete3 / inclusive / pset get p_bndry
|
||
</code></pre></div></div>
|
||
|
||
<p>Next, add the integer cell attribute <code class="language-plaintext highlighter-rouge">id_in_out_bndry</code>:</p>
|
||
|
||
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>cmo / addatt / MONAME / id_in_out_bndry / vint / scalar / nelements
|
||
</code></pre></div></div>
|
||
|
||
<p>and ‘color’ it based on the three element sets created above:</p>
|
||
|
||
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>cmo / setatt / MONAME / id_in_out_bndry / 1 0 0 / 4
|
||
cmo / setatt / MONAME / id_in_out_bndry / eltset get e_delete3 / 3
|
||
cmo / setatt / MONAME / id_in_out_bndry / eltset get e_delete2 / 2
|
||
cmo / setatt / MONAME / id_in_out_bndry / eltset get e_delete1 / 1
|
||
</code></pre></div></div>
|
||
|
||
<p>All elements colored 4 (the default value for <code class="language-plaintext highlighter-rouge">id_in_out_bndry</code>) are elements
|
||
who evaluate false for all of the above <code class="language-plaintext highlighter-rouge">eltsets</code>.</p>
|
||
|
||
<p>Create an element set for all <code class="language-plaintext highlighter-rouge">id_in_out_bndry(cell_i) == 4</code>:</p>
|
||
|
||
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>eltset / e_delete4 / id_in_out_bndry / eq / 4
|
||
eltset / e_delete3 / id_in_out_bndry / eq / 3
|
||
eltset / e_delete2 / id_in_out_bndry / eq / 2
|
||
eltset / e_delete1 / id_in_out_bndry / eq / 1
|
||
</code></pre></div></div>
|
||
|
||
<p>Finally, remove all elements ‘colored’ by method 3 and all elements <em>not</em> colored by any of methods 1, 2, or 3:</p>
|
||
|
||
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>rmpoint / element / eltset get e_delete4
