We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.
Q : What value of faces per cluster should be used in S2S radiation model in ANSYS Fluent..?
A : 1) For the face to face option while using the S2S radiation model in ANSYS Fluent, the number of faces per cluster needs to be defined as user input.
2) The solver clubs these many number of elements on a surface and stores their weighted average value of view factors as the cluster view factor for radiation heat transfer calculations.
3) These number of faces per cluster should be defined considering different parameters: (a) the mesh resolution ( surface mesh elements ); lower the value for coarser mesh and vice versa (b) the temperature gradient expected ( lower value for high gradients ) (c) parts shape/geometry ( lower the value of complex shape parts, etc. )
