View Factor Computation

Application ID: 20701

When simulating surface-to-surface radiation, we rely on the view factors between elements of diffuse surfaces that emit and receive radiation. To compute surface-to-surface radiation in a given geometry, operators are created by the heat interface and can be used to evaluate view factors in postprocessing.

This model shows how to compute view factors using the operators provided by surface-to-surface radiation features. The geometric configuration consists of two concentric spheres, and the results include computed view factors, which are compared with analytical values.

This model example illustrates applications of this type that would nominally be built using the following products:
