The following table provides a non-exhaustive list of local variables which are used in the code in a recurring manner.

C code	Description
cell_id	Cell index
face_id	Face index
tr_dim	Indicator for tensor perodicity of rotation
i_massflux	Mass flux at interior faces
b_massflux	Mass flux at boundary faces
i_visc	at interior faces for the r.h.s.
b_visc	at border faces for the r.h.s.
rhs	Right hand side

Local naming convention for fields (C)

Rules have been established for local names denoting fields, depending on their nature. The convention is as follows:

• The first letter of the name indicates the location at which the field values are defined:
  • c for values at the cell centers.
  • i for values at the interior faces.
  • b for values at the boundary faces.
• The next three letters indicate if the field is a variable (at the current time step or the previous time step) or a property:
  • var for variables at the current time step.
  • vara for variables at the previous time step.
  • pro for properties.
• An underscore _ follows.

The following examples illustrate this convention:

cvar_pr: Values of the variable pressure field defined at the cell centers, at the current time step.
cvara_pr: Values of the variable pressure field defined at the cell centers, at the previous time step.
cpro_cp: Values of the property specific heat defined field at the cell centers.
