About mapMethod of mapFields in openfoam

Hi guys,
I have confuse about the mapMethod of mapFields in openfoam. For now , I know that there are three methods of mapping in openfoam : mapNearest, interpolate and cellPointInterpolate respectively, which can be seen in mapFields.C of v2106 or v2112, the path of your openfoam directory maybe $FOAM_APP/utilities/preProcessing/mapFields/mapFields.C.
But online document of openfoamv2112, there are 4 methods of mapping, clicks

HTML Code:

https://www.openfoam.com/documentation/guides/latest/doc/guide-fos-field-mapFields.html#autotoc_md1503

to see. The methods are not mentioned in mapFields.C.
Now how could I use the methods not mentioned ?
If you have some advice, please let me know, thank you for your effort in advance!

Hi,

You are simply referring to two separate things. One of them is the utility mapFields and the other is the functionObject mapFields. The latter maps input fields from local mesh to secondary mesh at runtime. An example of its usage can be found in

HTML Code:

$FOAM_TUTORIALS/incompressible/pimpleFoam/laminar/cylinder2D
