View Factor Extraction in Ansys Mechanical

    • Filippo Timperi

      Hello everyone, I am using Ansys Mechanical to perform a thermal analysis. I am looking for a way to extract the view factors for each surface in each enclosure in my model.
      Can anyone help me with this?
      Thank you very much in advance🙂

      In Mechanical you can use Radiation > Surface-to-surface and indicate the surfaces that will be radiating to each other. This will automatically calculate the view factors during solution and perform the radiation calculations. 

      Please refer to for further details. During simulation viewfactors are computed for each element face. So, for example, if you have 1000 element faces that form a radiation enclosure you will have a 1000x1000 matrix. To get the average view factor between a source set of radiation faces and target set of radiation faces the VFQUERY APDL command can be used. This is not directly exposed in Mechanical.
