XGC-A04: Increased particle transport in the SOL region
The particle diffusivity in the outside separatrix region has been increased from 0.05 to 0.5 
tbl_D_coeff2=0.5D0 ! m^2/sec, D_turb for outside of separatrix (SOL+private flux region)
The resulting plasma density profile is identical to the profile obtained in the case XGC-A03.
This problem is likely related to a mistake in the particle diffusivity implementation in the SOL region.
Hi Alexei,
Looking at your reports for the last few days, I think you are concerned about the rise of ne for rho > 0.95 in the final time slice. Is that correct?
What is the model for the particle source? Is it Degas or something more phenomenological, such as prescribing a source rate at the wall?
What is the parallel particle transport in the SOL?
