Hi,

I have found an error in the code.
The 2D "standard" diffusion algorithm may be incorrect. The stencil shown in Weickertt (2002) is not the same as that referenced (from the handbook volume 2). That stencil has both terms in the top-left and bottom left corners negative. I beleive it is a typo in the Weickertt paper unless I am missing something.
