Pb_multiphase Implementation

This subsection documents how the Pb_multiphase module is implemented within the TrioCFD/TRUST framework: the code and folder architecture, the structure of the system of equations and the matrix-filling principle, the evanescence operator that drives phase/model management, and the discretization schemes used. It is the implementation counterpart of the physics-oriented Multiphase Flow section.

The averaged Euler-Euler (two-fluid) model is solved by two problems, Pb_multiphase and its reduced Pb_multiphase_HEM variant; the pages below describe how they are programmed.
