Operator Overview

Operators in GUERNICA are modular and are enabled through the [components] section of the input file, specifically through the operators entry. This allows each simulation to include only the physical processes needed for a given case.

Some operators require certain species to be present in the simulation. Species are specified through the species entry under [components]. Although multiple species may be included as prescribed background populations, GUERNICA itself evolves only the neutral distribution function in time. Plasma quantities are therefore treated as inputs to the neutral solver rather than as independently evolved kinetic species.

For each species listed in the simulation, the initial distribution function is defined in a [<species>:init] section. Any spatial dependence used by that initialization is then specified separately through one or more [profile:<name>] sections. This separation allows a distribution type and a spatial profile to be combined flexibly when setting up a case.

A complete list of available distribution function initialization types and profile types is provided in Inputs Reference.
