Discretization in time: Several time steps (16) to study the evolution of pressure during the transition phase until it stabilizes. The time pattern is implicit (\(\vartheta =1\)).
List of calculation times in seconds:
\(\mathrm{1,}\mathrm{5,}\mathrm{10,}\mathrm{50,}\mathrm{100,}\mathrm{500,}{10}^{3},{5.10}^{3},{10}^{4},5.{10}^{4},{10}^{5},5.{10}^{5},{10}^{6},5.{10}^{6},{10}^{7},{10}^{10}\)
The nodal unknowns, fluid pressures evaluated in Code_Aster, are variations from the initial reference pressures defined under the keyword THM_INIT, which is why this table shows pressure variations in our comparison between the Code_Aster calculation and the reference solution.
