Fourier - Heat Conduction
Click on the dropdownbox 'Initial Temperature' and select f(x) = Ax + B
The graph of the temperature distribution in a rod (100 0 and 0 0 degrees in the two ends).
Mark the checbox 'Current' and use the scrollbar 'n = ' to see the elements in the Fourier Serie that represent the temperature of the periodic temperature distribution.
Mark the checkbox 'All' and use the scrollbar 'N = ' to see all the terms in the Fourier Serie.
Mark the checkbox 'Sum' and use the scrollbar 'N = ' to see the sum of elements in the Fourier Serie.
Set the scrollbar 'N = ' to the value 100.
The red graph now shows the sum of the 100 first elements in the Fourier Serie.
Use the scrollbar 't = ' to see the temperature distribution at different time and position.
Use can change the factor A in the temperature distribution f(x) = Ax + B You can also change the diffusivity k.
