Characteristics of modeling

Loading and boundary conditions are modelled by:


* On face :math:`\mathrm{D1}`, move to :math:`Y` drawn


* On face :math:`\mathrm{D3}`, imposed traction

In addition, a uniform and constant temperature of :math:`20°C` and a uniform and constant drying field of 1 are imposed on the structure. The sorption‑desorption curve (user data) makes it possible to go from the drying variable to the humidity.

Tested sizes and results
------------------------------

We test the values of :math:`{\varepsilon }_{\mathrm{xx}}^{\mathrm{fl}}` and :math:`{\varepsilon }_{\mathrm{yy}}^{\mathrm{fl}}` at node :math:`\mathrm{N5}`, for the times 45, 245, and 365 days.
