How to set line source of emission

Hi Foamers,

I want to set line source of emission (or point source) at the ground wall. Can anyone give me any idea?

Hi, I am interested in the answer too. Did you find any solution? Actually, I succeed in using fvOptions to create a line source (approximated by a narrow band on the groundWall).
However, the line source is strongly affected by the mesh. Namely, with a unstructured mesh, I am unable to get an exact narrow-band.

Hi,
I am using the "funkySetFields" utility.
See the following link for the tutorial.
