PhysicsDataExplained
v15 v16 7 7 This contains only one namelist: {{{PhysicsData}}}. 8 8 9 == A Note On Extraneous {{{PhysicsData}}} Members == 10 11 Some of the parameters in the {{{PhysicsData}}} namelist do not currently serve any purpose. Most of these physical parameters were originally used in features that we have not yet ported over from AstroBEAR 1.0. They were left in {{{PhysicsData}}} against the day that we do get all those features moved over, but do not currently have any effect on the code. 12 13 This page deals with parameters that have an effect on AstroBEAR 2.0; as such, we won't bother discussing extraneous namelist members. If a parameter in {{{physics.data}}} is not covered here, then assume it has no impact on your simulation. If it turns out it does, however, then please update this page. 9 14 10 15 [[BR]] … … 12 17 * '''''{{{gamma:}}}''''' The constant ideal gas value of [[latex($\gamma$)]]. AstroBEAR generally assumes that the gases within the problem domain are monatomic, so [[latex($\gamma$)]] should be {{{1.6667}}} for non-isothermal problems. For isothermal problems we use {{{1.001}}}. Normally [[latex($\gamma_{isothermal} = 1$)]], but a [[latex($\gamma$)]] of exactly 1 is hard for our solvers to process, so we just get as close to 1 as we can. 13 18 14 * '''''{{{gammac:}}}''''' The isentropic gamma of a real gas. This feature is not yet implemented in AstroBEAR 2.0, so this parameter can be ignored. 15 16 * '''''{{{Xmu:}}}''''' The mean molecular weight of the gas. Generally specified to be 1.0 for Hydrogen. 19 * '''''{{{Xmu:}}}''''' The mean molecular weight of the gas. Generally specified to be 1.0 for hydrogen. 17 20 18 21 [[BR]]
