pure virtualinherited

This method computes the flux limiting ratio based on the provided scalar values, gradient vectors, direction vector, maximum and minimum allowable values, and geometric information from the face and cell centroids.

It must be overridden by any derived class implementing a specific limiting strategy.

Template Parameters
TThe data type of the field values and the return type.
Parameters
phi_upwindThe field value at the upwind location.
phi_downwindThe field value at the downwind location.
grad_phi_upwindPointer to the gradient of the field at the upwind location.
grad_phi_downwindPointer to the gradient of the field at the downwind location.
dCDA constant direction vector representing the direction of the cell face.
max_valueThe maximum allowable value.
min_valueThe minimum allowable value.
fiFaceInfo object containing geometric details such as face centroid and cell centroids.
fi_elem_is_upwindBoolean indicating if the face info element is upwind.
Returns
The computed flux limiting ratio.

This pure virtual function is intended to be defined in derived classes, which will implement the specific limiting algorithm. Derived classes will provide the actual logic for computing the flux limiting ratio, ensuring that the result adheres to the constraints and properties required by the specific limiting method.
