Detailed Description

Parameters and functions for the first SPH smooth: density and velocity derivatives.

Constructor & Destructor Documentation

DenDvDxSmoothParams::DenDvDxSmoothParams ( int  _iType, int  am, CSM  csm, double  _dTime, int  _bActiveOnly, int  _bConstantDiffusion, int  _bStarting, int  _bHaveAlpha, double  _dAlphaMax  )

inline

Parameters

_iType	Type of particle to operate on
am	Active rung
csm	Cosmology information
_dTime	Current time
_bActiveOnly	Only operate on active particles.
_bConstantDiffusion	Fixed diffusion constant
_bStarting	Simulation is starting
_bHaveAlpha	No need to calculate alpha
_dAlphaMax	Maximum SPH alpha

Member Function Documentation

void DenDvDxSmoothParams::combSmoothCache ( GravityParticle *  p1, ExternalSmoothParticle *  p2  )

protectedvirtual

combine cache copy with home particle

Parameters

p1	pointer to "home" particle data
p2	pointer to particle data being flushed back from a remote treepiece.

This method enables commutative/associative operations to be performed on remote data by combining data accumulated by a remote processor in p2 with the data on the home particle, p1. Any accumulators used in this function should be initialized in initSmoothCache() to avoid double counting.

Implements SmoothParams.

void DenDvDxSmoothParams::initSmoothCache ( GravityParticle *  p )

protectedvirtual

initialize particles as they come into the cache

Parameters

p	pointer to incoming particle data from remote processor

Implements SmoothParams.
