Flag storing which predefined post-processing has to be done
| pressure_bc_defs |

| pressure_bc_is_owner |
True if the definitions are stored inside this structure, otherwise the definitions are stored inside a dedicated cs_equation_param_t if an equation solves the pressure field.
| pressure_ic_defs |
Pointers to the definitions of the initial conditions associated to the pressure. In order to force a zero-mean pressure, the code can compute the average of the resulting pressure and subtract it
| pressure_ic_is_owner |
True if the definitions are stored inside this structure, otherwise the definitions are stored inside a dedicated cs_equation_param_t

| velocity_bc_is_owner |
True if the definitions are stored inside this structure, otherwise the definitions are stored inside a dedicated cs_equation_param_t Most of the time this should be false since an equation is associated to to the resolution of the velocity field (the momentum equation).
| velocity_ic_defs |
Pointers to the definitions of the initial conditions associated to the velocity. The code does not check if the resulting initial velocity satisfies the divergence constraint.
| velocity_ic_is_owner |
True if the definitions are stored inside this structure, otherwise the definitions are stored inside a cs_equation_param_t structure dedicated to the momentum equation.
