Characteristics of the mesh
----------------------------

Number of knots: 726.

The volume cells are 500 HEXA8 hexahedral meshes.


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

The water concentration is tested over 10 knots spread across the thickness at three times (5, 15 and 54 years):
