    Fluid turbulence modeling of the Scrape-Off Layer (SOL) using codes that relax the usual scale separation paradigm in the SOL and treat fluctuations and time averaged background profiles on the same footing.has been an area of promising progress. Excellent progress has been achieved with the ESEL code simulating the SOL of smaller devices and the higher temperature SOL of JET. Compared to the SOL of smaller devices the SOL of JET seems to exhibit more 3D effects which are not included in the 2D nature of the original code, which presumes the absence of drift waves in the edge, and – more importantly – uses plasma streaming off with ion sound speed in the parallel direction for the SOL. We have compared several approaches to these 3D effects and numerically investigated the SOL plasma response to a source that has a complex non Gaussian PDF.
