How to access the field of weighting factor of interpolations
 
Hi,

I'd like to access and use the weighting factor used in interpolations.
When I use the setting "interpolate(U) linear", I'd like to access the
weighting factor w in the following equation:

U_f = w*U_P + (1-w)*U_N

Could you tell me how to access the field(maybe surfaceScalarField)
of the weighting factor for the interpolation schemes defined in fvSchemes?

Thanks in advance,
Fumiya

For linear interpolation "mesh.surfaceInterpolation::weights()" should work (surfaceScalarField).

Lieven

Thank you for your reply. That works fine for linear interpolation.
Is there a more general way to access weighting factors for other
interpolation schemes different from the central differencing?

Thank you for your help,
Fumiya
