Dear all,
Is there a way to interpolate a preliminary solution (calculated with an external code) in an existent OpenFOAM grid?
I was thinking about a .csv or .txt file to be interpolated on an existent OpenFOAM grid.
The file should be structured somehow like this:

x,y,z,p,Ux,Uy,Uz
0,0,0,1000,1,0,0
0.1,0,0,1000,1,0,0
...
1,1,1,1000,1,0,0

I checked the conversion methos available in OpenFOAM but they are related to the conversion of a mesh or to the conversion of another commercial software input (fluent3DmeshToFoam and similar).
I found something in the sampleDict function, it allows to save solution in a raw format, however it works only to export the solution, not for the import.
I tried with mapFieldsbut it works only with other openFoam solution.
I alos checked different other utilities in openFoam but none of them seems to be helpful.
Can anyone suggest me an utility or a method to achieve this interpolation?
Thanks!
