Installation and License Questions / max_force_threshold

« on: December 27, 2025, 07:44 »

Hello,
My script involves:

method = NVEVelocityVerlet(
    initial_velocity=ConfigurationVelocities(remove_center_of_mass_momentum=True),
    max_force_threshold=10.0 * eV / Angstrom,
)

Here, "max_force_threshold=10.0 * eV / Angstrom," somehow, causes an error:

"NL.ComputerScienceUtilities.Exceptions.NLTypeError: The parameter, max_force_threshold, must be a PhysicalQuantity with units of eV/Ang."

I believe, it should normally work but it ends up with this error.

Thanks for your help in advance,

General Questions and Answers / Can we mimic neutron stars?

« on: November 2, 2021, 21:05 »

Hello,

One of my colleagues is asking if we can build layered structures to mimic neutron stars. What we know is that the surface of a neutron star can be treated like a structure formed by iron.

Thank you,
