11. Modeling I#

Fluid behavior: THMC = LIQU_SATU

11.1. Characteristics of modeling I#

  • Volume modeling

  • 1 mesh HEXA20 from 3D modelling_ THMD: THM_HEXA20D

It is the same modeling as \(G\) but in lumpé (integration at the vertices). The results will therefore be significantly different from the reference case. This is therefore a case of non-regression.

11.2. Tested sizes and results#

Since this test is non-regression, 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 \((\vartheta =1)\).
