I got a solution to the heat equation using Fourier transforms with the special case g(x) = GH(x-a)(adsbygoogle = window.adsbygoogle || []).push({});

u(x,t) = G/2[1+erf(x-a/(2[tex]\sqrt{t}[/tex]))]. But I just wanted to know what this special case represents physically.

I should probably ask what does any special case to the heat equation represent physically.
