v7.32.129 WTNP129 — HM modeling of a bar saturated with compressible liquid

Summary:

Here we study an HM problem saturated with liquid in dimension 2. Given the symmetries of the problem being treated, the solution is one-dimensional. The structure is subjected to hydraulic pressure imposed on its upper part. Its mechanical behavior is elastic. The purpose of this test is to test the resolution by coupling (see documentation « Instructions for using the model THM » [U2.04.05])

So we have 3 models in this test:

• Modeling A: the physical problem is solved using the « classical » method, by global coupling

• C modeling: This modeling is identical to modeling A but with the sub-integrated element HM_SI
