Peridynamics m_taubi units


In the Peridynamic viscoelastic solid model (ves), shouldn’t the units for m_taubi be time and not unitless since it is a relaxation constant? The LAMMPS documentation says it’s unitless (

In LAMMPS custom “time constants” are number of timestep sizes, so they are indeed unit less - since the timestep size already contains the unit of time. Think of it as the tdamp and pdamp time constants for thermostat and barostats.
