The following is the simulation of the diffusive transport equation in 1d :

(d/d_{t})F+u*(d/d_{x})*F-k*(d^{2}/d_{xx})*F = 0

where *u* is the velocity of the particle being transported.

In the example, we are transporting a senoid wave from left to right. You can change the velocity and the coefficients of diffusion modifying the parameters u and k in the 'globals' button.

You can experiment making the equation diffusive-dominant, or convective-dominant.
