v7.20.102 HSNA102 - Validation of drying laws on a cylindrical concrete test piece

Summary:

This test case is intended to validate the calculation of concrete drying, developed in the Code_Aster nonlinear thermal operator. Here we test the various diffusion laws available in Code_Aster, namely SECH_GRANGER, SECH_MENSI, SECH_BAZANT and SECH_NAPPE. However, the possible temperature dependence of the models is not tested.

This is an axisymmetric test case where the water concentration is applied directly to the outer wall. The results are compared with a numerical solution of the equations using Scilab.
