Dear experts,

I have generated a surface scalar field phi output in openfoam. The data are written as a list for e.g.

internalField nonuniform List<scalar>
84816
(
0.00097686221180306163393
-1.2934803937188405545e-06
-3.593104329749689473e-07
-4.4873432280630928465e-06

.....

}
walls
{
type calculated;
value nonuniform List<scalar>
2400
(
6.5475123649135464981e-05
6.7322449751017600459e-05
6.8555470186164915161e-05
6.9186374210746860204e-05

....


To visualize these data in paraview, I have used the command

foamToVTK -surfaceFields

I opened the .vtp file in paraview and added a glyph filter to visualize them.

I face two issues here.

1. Although they are scalar field, after applying glyph, they are shown as a vector field, phi x, phi y, phi z. How to visualize them as a scalar value?

2. My intention is to visualize the phi value only on wall boundary, but there is no option to choose inlet, outlet, wall patch to be activated for these surface scalar fields in paraview. Is there something I can do during using foamToVTK command ? I tried using foamToVTK -no-internal -surfaceFields, but it did not generate vtk corresponding to only boundary phi values.

Any help is very much appreciated.

Thanks
