Evolution Aggregation Equation

We solve the two dimensional aggregation-drift equation with interaction potential $W(x) = |x|^2/2 - \ln(|x|)$ and drift potential $V(x) = -(1/4) \ln(|x|)$. The computational domain is [-1.5,1.5]$\times$[-1.5,1.5]. We simulate the long time behavior of a solution of the aggregation-drift equation with a non-radially symmetric initial data, given by five Gaussians to the same equilibrium profile.
