# Template vpl.in file for vspace generation of files for habitable planet tidal heat survey
sSystemName tsync # System Name
iVerbose 5 # Verbosity level
bOverwrite 1 # Allow file overwrites?
# All space after a # is ignored, as is white space
# The first lowercase letter(s) denote the cast: b=boolean, i=int, d=double,
# s=string. An "a" indicates an array and multiple arguments are allowed/expected.
# List of "body files" that contain body-specific parameters
saBodyFiles star.in $ # Star's input file
planet.in # Planet's input file
# Array options can continue to the next line with a terminating "$". The $ can be
# at the end of the string or not. Comments are allowed afterwards.
# Input/Output Units
sUnitMass Solar # Options: gram, kg, Earth, Neptune, Jupiter, solar
sUnitLength AU # Options: cm, m, km, Earth, Jupiter, solar, AU
sUnitTime year # Options: sec, day, year, Myr, Gyr
sUnitAngle d # Options: deg, rad
sUnitTemp K # Options: Kelvin, Celsius, Farenheit
# Units specified in the primary input file are propagated into the bodies.
# Otherwise specifiy units on a per body basis in the body files.
# Most string arguments can be in any case and need only be unambiguous.
# Input/Output
bDoLog 1 # Write a log file?
iDigits 6 # Maximum number of digits to right of decimal
# Evolution Parameters
bDoForward 1 # Perform a forward evolution?
bVarDt 1 # Use variable timestepping?
dEta 0.01 # Coefficient for variable timestepping
dStopTime 1.0001e10 # Stop time for evolution
dOutputTime 1.0e9 # Output timesteps (assuming in body files)
# Option names must be exact in spelling and case.
# If no forward or backward integrations are requested, but a log file is, then
# the log file will be generated. Useful for parameter space surveys.
# Some options are only permitted in the primary file, some are forbidden.
# See the online documentation of vplanet for the rules
