Hi all

I'm doing a study with a 2D axisymmetric setting. In this study, there is a particular zone that acts as an energy source. This semicircular zone is intended to be rotated about the axis to model a spherical region of plasma.

Now, I have defined an energy source term within that zone, and I know the total energy deposited per second within the sphere (7W), and I know that this small region has a radius of 0.25 mm.

Now, calculating the volumetric heating as simply Power/Volume results in a figure of the order 10^10 W/m3

Now, my question is this: I'm unsure if I should be calculating the volumetric heating based upon the volume, as I've done above, or if I should simply calculate it over the semicircular area, which is then integrated around the axis BY FLUENT automatically - I have no idea what Fluent would actually do, so I'm hoping someone who's experienced in axisymmetric solution can advise me on this.

Thanks in advance.

You need to give the full source as like 3D analysis. No need to convert the source to axi symmetric analysis.
With regards,
