Hello,

I am trying to map data to an internal field (i.e. over a flat plane within the domain). According to documentation, I can do it using mapFields's cuttingPatch.

patchMap
(
   <coincident patches in the two cases>
);
 
cuttingPatches
(
   <target patches who has to be mapped from the original internal field now cut by patches>
);

- First of all, I do not have the first case. I want to initialize data in a small plane within the domain. So, patchMap will remain empty.

- I do not understand what " <target patches who has to be mapped from the original internal field now cut by patches>" means. I do not have a second case. Can somebody describe me a way to map data to an internal field?


Cheers,
CYln

You can try using setFields to set your variables, while defining the plane with topoSet or cellSet (i can't remember wich of both worked for me).

I guess this refers to the mapFields utility which can be used to map data from one case to another. mapFields supports mapping data from and to case of different mesh size, which is where cutting patches (e.g. the mesh of the second case larger mesh may be cuttion through the patches of the smaller first mesh) come into play.
