setExprFields with surfaceScalarFields

Hi,

I have been trying to create surfaceScalarFields from setExprFields.

This utility needs a flag for the oriented keyword (at least I recognize the dot product with the surface area vector and include the oriented keyword).

This will cause problems in multiprocessor calculations as the values seem to be wrong when the oriented keyword is not present.

Tested on OpenFoam: v2212 with pitzDaily tutorial.

If more information is required, please let me know.

Best Regards
