12. J modeling#
Fluid behavior: THMC = LIQU_SATU
12.1. Characteristics of J modeling#
Volume modeling
1 mesh HEXA20 from 3D modelling_ THMS: THM_HEXA20S
It is the same modeling as \(G\) but selectively (integration at the vertices for the evolutionary terms and at the Gauss points for the others). The results will therefore be significantly different from the reference case. This is therefore a case of non-regression.
12.2. Tested sizes and results#
Since this test is a non-regression test, we are satisfied with a simple validation over 2 moments.
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 \((\vartheta =1)\).
