| 33 | |
| 34 | This namelist controls the options associated with the sweep integration scheme. It will only be used if the {{{iScheme}}} option in {{{SolverData}}} is set to 1. |
| 35 | |
| 36 | '''NOTE:''' There are several deprecated options in the {{{SweepData}}} namelist right now. If you see a particular option in an older data file that isn't discussed here, it is probably deprecated and therefore of no consequence. |
| 37 | |
| 38 | |
| 39 | * '''''{{{lChar_Limiters}}}''''': Controls whether characteristic variablers are used instead of primitive variables in certain parts of the sweep scheme. By default, this is set to {{{.true.}}} |
| 40 | * '''''{{{lCTU}}}''''': A boolean flag controlling the corner transport upwind method. This should always be set to {{{.true.}}} |
| 41 | * '''''{{{lCautious}}}''''': When set to true, AstroBEAR protects hyperbolic quantities when solving. In general, this should be set to {{{.true.}}} |
| 42 | * '''''{{{lLimiter}}}''''': Controls the use of [http://en.wikipedia.org/wiki/Flux_limiter slope limiters]. This should always be set to {{{.true.}}} |
| 43 | * '''''{{{InterpOrder}}}''''': Sets the interpolation order to be used during variable reconstruction. AstroBEAR has three options for this: |
| 44 | * {{{1 -- Constant Interpolation}} |
| 45 | * {{{2 -- Linear Interpolation}}: WARNING: this option is not well-tested. |
| 46 | * {{{3 -- Parabolic Interpolation}}: This is the default option. |
| 47 | |
| 48 | * '''''{{{ViscCD}}}''''' Controls AstroBEAR's numerical viscosity options. {{{ViscCD}}} currently has three options: |
| 49 | * {{{0 -- ROE_VISCOSITY}}}: The default option, this value turns viscosity off. |
| 50 | * {{{1 -- ROE_VISCOSITY}}}: ! 0 = NO_VISCOSITY, 1 = ROE_VISCOSITY, 2 = H_VISCOSITY |
| 51 | lApplyLOF = .false. ! Apply local oscillation filter (reduces carbuncles) |
| 52 | LOF_ALPHA = .075 ! Strength of local oscillation filter. |
| 53 | iTracer = 0 ! 0 = Normal Tracers, 1 = Lagrangian Tracers |
