3. Modeling A

3.1. Characteristics of modeling

It is axisymmetric modeling.

Divided into 10 elements of variable size on the thickness, 2 elements on the height.

3.2. Characteristics of the mesh

Number of knots: 55

Number of meshes and type: 20 QUAD4

3.3. Tested sizes and results

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