for consistency with fvModels and fvConstraints, to simplify code and case maintenance and to avoid the potentially complex functions entries being unnecessarily parsed by utilities for which functionObject evaluation is disabled. The functions entry in controlDict is still read if the functions file is not present for backward-compatibility, but it is advisable to migrate cases to use the new functions file.

Description
|
|
Calculates lift, drag and moment coefficients by summing forces on
|
|
specified patches for a case where the solver is compressible; i.e.,
|
|
pressure has units of kg/m/s^2 (Pa).
