VVinitial
VVinitial is a specification used in computational science to describe how vector-valued initial conditions are represented for simulations. It provides a standardized way to encode the starting state of systems described by vector fields, such as fluid velocity, magnetic fields, or force distributions, ensuring reproducibility across different codes and platforms.
Its origin lies in collaborative efforts in the mid-2010s to improve reproducibility in multi-physics simulations. The
Core features include a compact description of the initial state: a base value for the vector field,
Usage and impact: VVinitial is used to initialize simulations in computational fluid dynamics, electromagnetism, atmospheric and
Limitations and status: As with any standard, adoption depends on community agreement and tool support. VVinitial
