+<p>
+This is a model for transport of heat without storing it; see also:
+<a href=\"modelica://Modelica.Thermal.HeatTransfer.Components.ThermalResistor\">ThermalResistor</a>.
+It may be used for complicated geometries where
+the thermal conductance G (= inverse of thermal resistance)
+is determined by measurements and is assumed to be constant
+over the range of operations. If the component consists mainly of
+one type of material and a regular geometry, it may be calculated,
+e.g., with one of the following equations:
+</p>
+<ul>
+<li><p>
+ Conductance for a <b>box</b> geometry under the assumption
+ that heat flows along the box length:</p>
+ <pre>
+ G = k*A/L
+ k: Thermal conductivity (material constant)
+ A: Area of box
+ L: Length of box
+ </pre>
+ </li>
+<li><p>
+ Conductance for a <b>cylindrical</b> geometry under the assumption
+ that heat flows from the inside to the outside radius
+ of the cylinder:</p>
+ <pre>
+ G = 2*pi*k*L/log(r_out/r_in)
+ pi : Modelica.Constants.pi
+ k : Thermal conductivity (material constant)
+ L : Length of cylinder
+ log : Modelica.Math.log;
+ r_out: Outer radius of cylinder
+ r_in : Inner radius of cylinder
+ </pre>
+ </li>
+</ul>
+<pre>
+ Typical values for k at 20 degC in W/(m.K):
+ aluminium 220
+ concrete 1
+ copper 384
+ iron 74
+ silver 407
+ steel 45 .. 15 (V2A)
+ wood 0.1 ... 0.2
+</pre>
