List of Run Input Parameter Grouping and their associated properties :

Name Description Caveats Properties
All settings for EPREM model 
All input settings for the EPREM model version 20181001
Name Label Description Caveats Units Default Value or Actual Value Valid Min Valid Max
numNodesPerStream numNodesPerStream 
Number of nodes per computational stream. Analogous to an 'r' resolution on a spherical grid.
 Must be at least one per process.
numRowsPerFace numRowsPerFace 
Number of streams in a row per computational face. Analogous to latitudinal resolution. There are six faces so the minimum stream resolution is 6 x rows x cols.
numColumnsPerFace numColumnsPerFace 
Number of streams in a column per computational face. Analogous to latitudinal resolution. There are six faces so the minimum stream resolution is 6 x rows x cols.
numEnergySteps numEnergySteps 
Number of steps on the energy grid. Works with eMin and eMax to determine the resolution w/ regards to energy. The energy grid is defined such that delta_lnp is uniform.
numMuSteps numMuSteps 
Number of steps on the pitch angle grid. The pitch angle grid is evenly spaced in cosine and goes from -1 to 1.
 The number of steps must be even.
rScale rScale 
The inner boundary of the simulation domain.
 If coupling to external MHD this parameter is set automatically. AU
flowMag flowMag 
Solar wind speed.
 If coupling to external MHD this parameter isn't used. cm/s
mhdDensityAu mhdDensityAu 
Number density at 1AU.
 If coupling to external MHD this parameter isn't used. #/cm^3
mhdBAu mhdBAu 
Interplanetary magnetic field strength at 1AU.
 If coupling to external MHD this parameter is not used. Gauss
simStartTime simStartTime 
The date for the simulation's first output step. This is arbitrary but useful for plotting a specific date range.
 JD
simStopTime simStopTime 
Simulation stop time. Relative to simStartTime and the time-step. The code will run until this date is reached.
 If coupling to external MHD this time is set automatically. JD
tDel tDel 
[JD] Simulation time step.
 If coupling to external MHD this is set automatically. JD
eMin eMin 
[MeV] Minimum energy for the energy grid.
 MeV
eMax eMax 
[MeV] Maximum energy on the energy grid.
 MeV
lamo lamo 
Parallel scattering mean free path at 1AU and 1GV.
 AU
mfpRadialPower mfpRadialPower 
Radial power for parallel scattering mean free path.
rigidityPower rigidityPower 
Rigidity scaling for the parallel scattering mean free path.
