Summary of simulations for the TTF meeting
Simulations for the TTF meeting are summarized on the attached Flash slides.
Simulations for DIII-D discharges 132014, 132016, 132017, and 132018 with theory motivated and imposed ExB flow shear suppression factors
The theory motivated flow shear suppression yields reasonable anomalous transport suppression level as one can see from the comparison below. Left panels show results with theory motivated factor with fm_cexb coefficient equal to 1, while the right panels show results with imposed flow shear factor.

The coefficient might need to be increased somewhat (especially in the SOL region).
Implementation of new version of the FMCFM interface is completed in the XGC-0 code
Multiple issues with the new version of FMCFM are finally resolved. The code is ready for production runs.
Problems with particle density evolution are fixed in the XGC-0 code
Problems related to recent merge to the svn repository are fixed. The problems were caused by incorrectly initialized fmcfm variables in the setup subroutine. The changes are committed to the repository.
XGC-A08/A09: testing changes in the code that related to problems with particle density evolution
Two input files are generated based on XGC-A07 input file: (1) XGC-A08: same equilibrium and same input file, but older version of the code; (2) XGC-A09: same equilibrium, newer version of the code, but older version of the flow shear suppression model. Left panels show results for the case XGC-A08 and right panels show results for the caseXGC-A09
Results clearly indicated that the problem has been introduced during the recent merge with the svn repository.
XGC-A07: new equilibrium and updated version of the code
The FMCFM changes has been synchronized with the version of the XGC-0 code from the svn repository. Gunyoung committed his changes related to the impurity radial model and get_mid_r bug. Theory motivated coefficient for the flow shear suppression factor is used. The simulation uses high resolution equilibrium provided by Rich Groebner. There are significant changes in the plasma density dynamics. It is not clear if these changes relate to (1) model for flow shear suppression factor; (2) new equilibrium; (3) other changes to the code. In order to isolate the problem, two new simulations are submitted: (1) XGC-A08: same equilibrium and same input file, but older version of the code; (2) XGC-A09: same equilibrium, newer version of the code, but older version of the flow shear suppression model.
XGC-N01: First simulation for the Alcator C-Mod discharge 1060510007.00844
Gunyoung has altered the original equilibrium that Jerry and Jim sent about two weeks ago to fit the XGC-0 requirements. The first XGC-0 simulation for this Alcator C-Mod equilibrium includes simplified model for the anomalous transport. The FMCFM interface is disabled.
XGC-A07: fm_web flows shear stabilization factor is decreased
The fm_web flows shear stabilization factor is decreased from 
Theory modivation coefficient for the flow shear stabilization factor
New XGC-0 namelist parameter is implemented in order to control parameter that is responsible for flow shear stabilization factor. According to Glenn’s notes, the fm_wexb coefficient should depend on
