FEM EquationHeat

Description
This equation describes the heat transfer in rigid and fluid bodies.

Usage

 * 1) After adding an Elmer solver as described here, select it in the tree view.
 * 2) Now either use the toolbar button [[Image:FEM_EquationHeat.svg|24px]] or the menu.
 * 3) Change the equation's solver settings or the general solver settings if necessary.

Solver Settings
For the general solver settings, see the Elmer solver settings.

The heat equation provides these special settings:
 * : There is also a residual-free-bubbles formulation of the stabilized finite-element method. It is more accurate and does not include any ad hoc terms. However, it may be computationally more expensive. If both and  are false, no stabilization is used and then the results might easily be nonsensical.

Equation:
 * : The type of convection to be used in the heat equation.
