Modeling A ============== In **modeling A**, we study the 2D structure with, first, the definition of the lower and upper lips of the crack and then by defining only the bottom node. Characteristics of the mesh ----------------------------- The mesh is shown in the following figure: .. image:: images/100000000000057F000002BF05B2DA76C1DB6B07.png :width: 6.8898in :height: 3.4425in .. _RefImage_100000000000057F000002BF05B2DA76C1DB6B07.png: It is composed of 296 knots for 513 TRIA3 elements. The crack bottom is composed of a single node located at coordinate :math:`(0.5\mathrm{,0}.5)`.
