00. Overview
The cooling by natural convection (steady-state analysis) is solved in this tutorial.
A heat source is placed on a substrate and the substrate is placed in the air.
The tutorial model Thermal Analysis (Watt) is solved using fluid-thermal analysis with external fluid flow taken into account.

Model
The substrate (VOL1) and the heat source (VOL2) are defined as box solid bodies. Heat quantity is specified to the body attribute of the heat source,
the external flow domain of the model is automatically created, and natural convection is set to it.
