Heat Capacitor

Lumped thermal element storing heat  Description The Heat Capacitor component models a generic ideal heat capacity. The heat capacity is set with property of Material and Volume. If the parameter ${T}_{0}$ is not set, this component assumes the default temperature of 293.15 $K$ at the start of the simulation. Equations $C\cdot \frac{\mathrm{dT}}{\mathrm{dt}}=\mathrm{port}.{Q}_{\mathrm{flow}}$ Variables

 Symbol Units Description Modelica ID $T$ $K$ Temperature T $C$ $\frac{J}{K}$ Heat Capacity C $\mathrm{port}.{Q}_{\mathrm{flow}}$ W Heat flow rate from port port.Q_flow Connections

 Symbol Default Units Description Modelica ID $\mathrm{Material}$ $\mathrm{SolidPropertyData}$ $-$ Solid material property data Material $\frac{W}{m\cdot K}$ Material.k is the thermal conductivity of the material Material.k $\frac{J}{\mathrm{kg}\cdot K}$ Material.cp is the specific heat capacity of the material Material.cp $\frac{\mathrm{kg}}{{m}^{3}}$ Material.rho is the density of the material Material.rho $V$ $1$ ${m}^{3}$ Volume of the node V $\mathrm{T__start}$ $293.15$ $K$ Initial condition of temperature T_start $\mathrm{fixed}$ $\mathrm{true}$ $-$ True enforces the T_start initial condition fixed Parameters for Visualization (Optional)

Note: If you enable Show Visualization option, you can visualize temperature change as colored geometry in 3-D Playback Window. To make this function available, you have to enable 3-D Animation option in Multibody Settings.
The quality of the visualization is affected if any open plot windows are behind the 3-D Playback Window. If you are experiencing playback issues, try moving the 3-D Playback Window so that it does not overlap a plot window. Alternatively, minimize or close any open plot windows.

(For more details about the relation between color and temperature, see Color Blend  help).

 Symbol Default Units Description Modelica ID $\mathrm{false}$ $-$ If true, you can visualize temperature of Heat Capacitor as colored sphere in 3-D Playback Window. And the following visualization parameters are available. VisOn $\mathrm{pos}$ $\left[0,0,0\right]$ $m$ Position of the node in visualization [X, Y, Z]. pos $\mathrm{R__sphere}$ $0.2$ $m$ Radius of visualized heat capacitor sphere. Sradius $\mathrm{Transparent}$ $\mathrm{false}$ $-$ If true, heat capacitor sphere is displayed as transparent. transparent $\mathrm{T__max}$ $373.15$ $K$ Upper limit of temperature in the color blend.
