Implementation ============= General diagram -------------- The general scheme of adaptation is shown in the figure. It includes the 4 phases described above: * resolution on one or more loading steps * adaptation of the mesh based on the calculation of an error indicator * projection of fields at the end of the last time step on the new mesh * balancing the fields at the end of the last time step on the new mesh .. image:: images/10000200000002F4000002D457EA7C7951AF176D.png :width: 4.0382in :height: 3.7354in .. _RefImage_10000200000002F4000002D457EA7C7951AF176D.png: Figure 4: Complete adaptation process example ------- An example of a practical implementation is shown in the test case*Code_Aster* SSNP158 [:external:ref:`V6.03.158 `].
