program_restrictions

These are general restrictions to the program.

Syntax

min_dimension_domain              = 1
don't change, only 1 makes sense

max_dimension_domain              = 3
don't change, only 3 makes sense

minimum-grid-factor               = 0.1d0
be careful, geometric series grow up very rapidly

maximum-grid-factor               = 10.d0
be careful, geometric series grow up very rapidly

delta-to-treat-grid-factor-as-one = 1.0d-3
to avoid numerical inaccuracies, everything in the interval 1+/- delta is treated as 1

minimum-grid-width                = 0.01d0
only a guess, if violated a warning message is printed to standard output

maximum-grid-width                = 200d0
only a guess, if violated a warning message is printed to standard output

maximum-number-of-grid-points     = 400000
only a guess, if exceeded a warning message is printed to standard output

lowest-temperature-allowed        = 1.0d0
in Kelvin [K]

Question

Can I change the lattice-temperature to 0 Kelvin in the input file?
