yes, this problem is quite usual .... just think about a simulation performend in the physical space, for example an exact projection with second order discretization. You will have a diverge-free...

if you want to simulate only the homogeneous/isotropic decay, you can simply work in the x,y plane by using the initial 1D distribution (extended in the homogeneous 2D meaning and adjusting the...
