The phrase "a very small time step" is correct and usable in written English.
It can be used in contexts related to physics, mathematics, or computer simulations where time intervals are discussed.
Example: "In our simulation, we need to use a very small time step to ensure accurate results."
Alternatives: "a tiny time interval" or "a minimal time step".
All computations were done under isobaric conditions, and, to capture the influence of all the reactions involved in the mechanism, a very small time step was used.
Meanwhile, it is also numerically illustrated that the discontinuity problem can be overcome by performing a very small time step immediately upon termination of the applied impulse.
By using Newmark's average acceleration method with a very small time step, subharmonic and chaotic responses have been obtained for certain parameter values.
By comparing results with a reference solution obtained with a very small time step, it is shown that the approximate solution is second-order accurate in time.
In order to avoid numerical instability, we must take a very small time step.
However, the state equation is still discretized in a very small time step to approximate the effect of continuous dynamics in [41].
The main reason is that, contrary to regular systems like, for example, the Solar System, resonant 3-body interactions often include very close encounters, which need a very small time-step size to be resolved accurately.
This includes hydraulics applications and leads to some drawbacks such as severe artificial pressure fluctuations and a limitation to very small time steps related to the WCSPH Mach number and explicit method.
Point kinetics equations are stiff differential equations, and their solution by the conventional explicit methods will give a stable consistent result only for very small time steps.
Modeling the foundation with zero mass would result in indefinite solutions and modeling the foundation with very small mass density would result in very small time steps, and make the analysis computationally inefficient.
The authors of the 2002 paper state that the somatic compartment was characterized by such high conductance densities that including capacitance necessitated very small time steps for accurate integration.
