v4.22.003 TTNL03 - Thermo-hydration. Simulation of an adiabatic test

Summary:

The purpose of this test is to validate thermo-hydrating behavior THER_HYDR, by simulating an adiabatic test:

a sample of fresh concrete is immersed in a calorimeter, the measurement being carried out with the release of heat, the aim is to find the temperature and hydration field over time.

The temperature and the degree of hydration are uniform in the sample. The temperature measured in the calorimeter will therefore be the reference solution, hydration being determined by analytic integration of the law of evolution.

2 models are proposed: three-dimensional and axisymmetric.
