Sauna 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 (except for heat sinks, see next paragraph). 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. For heat sinks, Sauna can perform an integrated fan/flow calculation. You just need to assign a fan curve to the flow network and Sauna will handle all of the flow/pressure calculations. Here again, however, this is handled without CFD. More details on the differences between Sauna and CFD programs are given here. Can AutoCAD files be imported? Can Pro-Engineer files be imported?
