# TRANSPORT COEFFICIENTS # ====================== # Set the parallel electron thermal conductivity. 1: fitted Balescu formulation from SOLPS5.0. 2: Older Braginskii SOLPS4.0 model. 3: 21-moment Balescu formulation. Default: 1 (integer) # 'b2tqxe_model' '3' # Nonzero: Modify the heat transfer model according to the 21-moment approach. This should only be used for multi-fluid runs. Default: 0 (integer) # 'b2trcl_lthf21' '1' # Nonzero: Modify vicosities according to the 21-moment approach. This should only be used for multi-fluid runs. Default: 0 (integer) # 'b2trcl_lvis21' '1' # Ballooning switches for adjusting the parallel profile of the radial transport: see 'b2tqna_balloonning' # Rescale all ion and electron transport coefficients in the PFR or divertor SOL. Default: 1.0 (real) # 'b2tqna_divsol_rescale' '2.0' # 'b2tqna_pfr_rescale' '2.0' # BOUNDARY CONDITIONS # =================== # Set the secondary electron emission coefficient at the divertor targets. 0: use cbsch(7,ireg) and/or gammae. 1: calculate locally according to a kinetic model. Default: 0 (integer) # 'b2stbc_secmodel' '1' # Turn on feedback mode for boundary conditions. Default: 0 (integer) # 'b2stbc_feedback' '1' # LABELLING THE SIMULATION # ======================== # Set the run number label. Default: 1000 (integer) #'b2mndr_run_number' '10' # Set the shot number. Default: 0 (integer) # 'b2mndr_shot_number' '17588' # CONVERGENCE TRICKS # ================== # Set the interval of CPU time after which the intermediate files plasmastate.xxxx are written. In case of a crash, the simulation can be recovered from these files. Default: 3600.0 (real) # 'b2mndr_savecpu' '3600.0' # Calculate running averages. Good for averaging EIRENE noise and gauging convergence. Default: 0 (integer) # 'b2mndt_av' '1' # Set minimum ion species density. Default: 1e4 (real) # 'b2mndr_na_min' '1e5' # Set ion density in the flat profiles solution. Default: 1e14 (real): # 'b2mndr_na_new' '1e15' # OUTPUT FILES # ============ # Set the number of time steps between writing out tallies. Positive: also writes tallies when the simulation finishes. Default: 1 (integer) # 'b2mndr_tally' '10' # Produce detailed output files of all B2.5 equation terms in all cells # 'b2wdat_iout' '4' # TURNING ON DRIFTS # ================= # There is a group of switches in b2ag.dat which allow flipping the magnetic field direction (for drift effect studies. # 'b2agfs_pit_rescale' '-1.0' # POWER BALANCE # ============= # Switch from solving the internal energy equation to the total energy equation. Default: 0.0 (real) # 'b2news_BoRiS' '1.0' # Switch groups which can turn off sources due to ionisation, recombination, heat loss, atomic physics etc.: see 'b2sqel_phm1' # MAIN ION SPECIES # ================ # Set the ion species number of the main ion species. Default: 1.0 (real) # 'b2mndr_ismain' '1'
