2D heat sources

      Hi,

      How can I convert the value of the 3d heat source into 2d axisymmetric case? Say I have a 100W losses in a straight cable. In 3D case I simply divide the source by the volume of the cable and apply it in Fluent as a source for cell zone in [W/m3]. How should I calculate this value in 2d axisymetric case?

      Best regards,

      Wojciech

      Exactly the same process. Fluent assumes the 2d model has a volume based on 1m (2d) and either PI or 2PI radians for 2d axi-symmetric (I can't remember which).
