    "Cutting:", "30 elements in length,"
    "", "2 elements in width."


Boundary conditions - loading (three calculations for three choices):


* scalar loads and dualization of the Dirichlet condition:


.. code-block:: text
 TEMP_IMPO (NOEUD = N1, TEMP_SUP = 0., TEMP_MIL = 0., TEMP_INF = 0.)
ECHANGE (GROUP_MA = GRSD1, COEF_H_SUP = 10., COEF_H_INF = 10. ,
TEMP_EXT_SUP = -50., TEMP_EXT_INF = -50.)
(GROUP_MA = GRSD2, COEF_H_SUP = 10., COEF_H_INF = 10. ,
TEMP_EXT_SUP = 50., TEMP_EXT_INF = 50.)


* constant function loads and dualization of the Dirichlet condition:

as above, but with constant functions having the same values.


* scalar loads and "kinematic" loading:


.. code-block:: text
 THER_IMPO: (NOEUD: N1, TEMP_SUP: 0., TEMP_MIL: 0., TEMP_INF: 0.)
