◆ create()

void ElasticDeformationSolver::create ( Storage storage,
IMaterial material 
) const
overridevirtual

Initializes all quantities needed by the solver in the storage.

When called, storage already contains particle positions and their masses. All remaining quantities must be created by the solver. The function is called once for every body in the run. The given storage is guaranteed to be homogeneous; it contains only a single material.

Parameters
storageParticle storage that shall be modified as needed by the solver.
materialMaterial containing parameters of the body being created. The solver can also set up necessary timestepping parameters of the material (ranges and minimal values of quantities).

Implements ISolver.

◆ integrate()

void ElasticDeformationSolver::integrate ( Storage storage,
Statistics stats 
)
overridevirtual

Computes derivatives of all time-dependent quantities.

The solver can also modify the quantities arbitrarily. It is however not recommended to perform the integration in the solver (using the time step stored in Statistics) as this is a job for timestepping. The solver can modify quantities using boundary conditions, inter-quantity relationships (such as the summation equation for density in SPH), clamping of values etc. It is also possible to add or remove particles in the storage and modify materials. Threads running concurrently with the solver must assume the solver can modify the storage at any time, so accessing the storage from different threads is only allowed before or after integrate; the is no locking for performance reasons.

All highest order derivatives are guaranteed to be set to zero when integrate is called (this is a responsibility of ITimeStepping implementation).

Parameters
storageStorage containing all quantities.
statsObject where the solver saves all computed statistics of the run.

needs to be generalized if particles with different materials interact
