6. D modeling

This test is very similar to B modeling. It allows you to test code coupling in MPI by replacing fluid-mechanical chaining by a weak coupling (without dependence of pressure on displacement).

Note: this test would be close to a coupling for fluid-structure interaction (IFS) if the pressure was dependent to the coordinates on the deformed surface whereas here it only depends on the original coordinates.

6.1. Characteristics of modeling

Here, a pressure field is defined on the fluid mesh depending on time and space. according to function \(1.E\mathrm{-}4\mathrm{\times }\mathit{INST}\mathrm{\times }(X+Y+Z)\).

This pressure field will be interpolated onto the solid mesh to serve as an input load.

The solid calculation is carried out at the times \(0.2\), \(0.4\),,, \(0.6\), \(0.8\) and \(1\).
