Computes a scalar variable defined as the skin-friction coefficient
- Args:
- source_parts:
Any boundary part(s) or a boundary part number.
- velocity:
A velocity variable.
- viscosity:
A viscosity variable or a value.
- free_density:
A constant ‘freestream density’ variable or a constant value(>0.).
- free_velocity_mag:
A constant ‘freestream velocity magnitude’ variable or a constant value(>0.).
- opt_for_a_gradient_of_velo_mag:
The gradient of the input velocity vector magnitude, or -1 to approximate it.
- output_varname:
The name of the newly created variable
- Returns:
New ENS_VAR instance or None
