SPH::SPHAdaptation Class Reference

Base class for all adaptations. The base class defines essential global parameters. It is also used for single-resolution method. In the constructor parameter, system_refinement_ratio defines the relation between present resolution to the system reference resolution. The derived classes are defined for more complex adaptations.

Detailed Description

Base class for all adaptations. The base class defines essential global parameters. It is also used for single-resolution method. In the constructor parameter, system_refinement_ratio defines the relation between present resolution to the system reference resolution. The derived classes are defined for more complex adaptations.
