## No Fields converted with "ensightWrite" FO with region different than region0

*In my process:*

1- I am mapping a VolScalarField (the pressure "p") from region0 on a targetMesh (coarser than region0) on the fly using the "mapFields" FO as:

```
meshInterp1
{
type mapFields;
libs ("libfieldFunctionObjects.so");
writeControl timeStep;
writeInterval 1;
mapRegion targetMesh;
mapMethod cellVolumeWeight;
consistent no;
fields (p);
patchMap ();
cuttingPatches (CONTOUR GAMMA_S GAMMA_E);
}
```

- Then:*

2- I want to use the "ensightWrite" FO on the fly during the execution to convert the pressure field from the OpenFOAM format to the Ensight one as:

ensightWrite_P { type ensightWrite; libs ("libutilityFunctionObjects.so"); writeControl timeStep; writeInterval 1; format binary; directory "postProcessing/EnSight/"; nodeValues yes; fields ( p ); region targetMesh; overwrite true; }

It seems the fields is not converted, only the mesh is present in the Ensigth directory but no fields data:

mapFields mapFields write: p: interpolated and written

ensightWrite ensightWrite write: ( )

but it seems working when I want to field on the "region0" as

ensightWrite_P { type ensightWrite; libs ("libutilityFunctionObjects.so"); writeControl timeStep; writeInterval 1; format binary; directory "postProcessing/EnSight/"; nodeValues yes; fields ( p ); // region targetMesh; overwrite true; }

it gives:

ensightWrite ensightWrite write: ( p ) End

It seems there is a problem with "region" argument in the "ensightWrite" FO
