Abstract:
How accurate are your thermal models? Few thermal analysts have the time and budget to test the convergence of their thermal models (e.g., SINDA models) as a function of mesh size. This paper presents guidelines for selecting mesh sizes and other simulation parameters to ensure accurate simulations.We considered the following aspects of thermal models: mesh size as determined by combined conduction, convection and radiation; perferred mesh geometries; treatment of boundaries and boundary conditions; and required time steps.
