Unformatted text preview: d Modeling Notes
An axisymmetric model is used for the cone. The radiating surfaces are modeled using three LINK32 elements.
The non-hidden method (VTYPE) is used since there are no blocking or obscuring surfaces within the enclosure
(i.e. all radiating surfaces fully "see" each other). The radiation matrix is written using 50 circumferential divisions
(GEOM). Since all the radiating surfaces form an enclosure, no space node is specified. Heat flux on the bottom ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 1–325 VM147
surface is applied using SURF151 (surface effect element). The value of Stefan-Boltzmann constant is specified
in consistent units as 5.6696E-8 W/m2-K. Results Comparison
