\section intro_poro Introduction
This function computes the porosity (volume factor \f$ \epsilon \f$
when porosity module is activated (iporos = 1 in cs_user_parameters.f90).
\section cs_user_poro_examples Porosity setting examples

\page base_poro_examples Setting porosity values: basic example
\section base_loc_var_poro Local definitions and initialization
\subsection mesh_quantities Mesh quantities
It may be useful to access some mesh adjacencies and quantities,
in which case local pointers allow for more readable code:
\snippet cs_user_porosity.c init_poro_mq
\subsection properties Associated properties
Accessing cell porosity property values is required so values may be set:
\snippet cs_user_porosity.c init_poro_pro
\section example_porosity Example: define porosity by geometric zones
Individual cell porosity values can be assigned to each cell, so
they may be based on groups, geometric criteria, or any other
time-independent functions:
\snippet cs_user_porosity.c set_poro_cells_1
Matching face equivalent surfaces should also be assigned in a
corresponding manner, for interior faces:
\snippet cs_user_porosity.c set_poro_i_faces_1
and for boundary faces:
\snippet cs_user_porosity.c set_poro_b_faces_1
