Heat Conduction with a Localized Heat Source on a Disk

Application ID: 17307


This classical verification model solves the steady state temperature distribution in a plan disk heated by a localized heat source at its center. It shows and compare different ways to define a heat source localized on a small domain by representing it either as a geometrical point or a small disk.

Both modelings have analytical solutions to which the obtained numerical results can be compared. The results bring guidelines to select the suitable option depending on the ratio between the source and surrounding geometry typical sizes.

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