 <p>As described in the <a class="reference internal" href="theory.html"><span class="doc">theory</span></a>, <strong>pycopm</strong> can be not only used for grid coarsening, but also to apply grid refinements, submodels, and transformations.
 Then, with the following commands first we substract a submodel around the isolated grid cell proyecting the outside pore volume on the boundaries, after
 we apply a grid refinement on the cells in the middle x and y location, and finally we rotate the model 45 degrees.</p>
