Nonradiating boundaries detected in the model

  • Node: Surface-to-Surface Radiation (rad)

  • Message: The list of features below use Opacity Controlled or None to define the emitted radiation direction. For the boundaries using Opacity Controlled option, if any, the domain opacities induce that no radiation is emitted. If these boundaries are not radiating, consider removing them from the Surface-to-Surface Radiation physics interface selection. Otherwise, check the domain and boundary opacity. Note that the layer opacity is controlled by the Layer Opacity subfeature.

  • List of features and corresponding nonradiating boundaries:   Diffuse Surface 1 (dsurf1): [1, 2, 3, 4, 5, 6, 7, 8]

This is a model sent to me by someone else, which runs normally on her computer, but this warning was reported on my computer. If I change the radiation direction, the final temperature result will be incorrect. Does anyone know how to solve this problem
