Construction of VolScalarField from surfaceScalarField

pakanatiakash · March 14, 2016, 08:44

Hi All

If I understood correct, I can use interpolate option to interpolate volume fields to surface fields (both vector and scalar). At the same time I can use reconstruct option to get back volume vector fields from surface fields.

I would like to know how to reconstruct volume scalar fields from surface scalar fields? As the reconstruct option would bring out a vector.

Looking for some quick answers!

Hello,

1- use the reconstructMag function (see finiteVolume/finiteVolume/fvc/fvcReconstructMag.C)

2- the only thing an open-source community cannot guarantee is the quickness of an answer

Hey

Thanks for the info

I'm just guessing here, but isn't reconstructMag(U) a short for reconstruct(mag(U))? I think that would return a volScalarField. You probably want reconstruct(U).

Hi Akash,

Have you tried

Code:

fvc::average(alpha_s)

?

I think what are you looking for fvc::average().

Check this post surfaceScalarField into VolumeScalarField

Best

What is this used for? converting volume to surface fields?
