Inaccurate radiation calculation

I tried a validation problem with fvDOM on axisymmetric case. The example case is attached.

Radiative analytical heat flux from "hot" wall comes out to 260.9 kW/m2.

Axisymmetric test case under-predicts the heat flux (15% error) (wedge patch)

Steps to reproduce:

  1. Download the zip
  2. Extract and execute Allrun (50 or 100 timestep entry is sufficient to analyze the issue)
  3. Observe qr field on hot and cold patches in paraview

Is there a way to solve this problem?

Thanks in advance!
