Sauna now includes a flow network feature. Does Sauna have computational fluid dynamics (CFD) capability?
No. With the flow network capability, the user can define a flow path (or paths) and Sauna will calculate the appropriate air temperature increase as air moves along the flow path. However, it is up to the user to specify all flow volumes. If the box has a straightforward flow path, the flow volume can be readily calculated by using the fan characteristics and box dimensions (or simply entered for what-if studies). The Sauna user manual explains how to perform flow calculations. More details on the differences between Sauna and CFD programs are given here.
