Boundary conditions and loads
-------------------------------------

Boundary conditions:


* All the nodes in the rigid plane are embedded.

3 charging cases:


* Normal pressure :math:`{P}_{n}=\mathrm{300N}/{\mathrm{mm}}^{2}`


* Normal pressure :math:`{P}_{n}=\mathrm{300N}/{\mathrm{mm}}^{2}` and tangential pressure :math:`{P}_{t}=178.2N/{\mathrm{mm}}^{2}`


* Normal pressure :math:`{P}_{n}=\mathrm{300N}/{\mathrm{mm}}^{2}` and tangential pressure :math:`{P}_{t}=181.8N/{\mathrm{mm}}^{2}`


Initial conditions
--------------------

None.
