Detailed Description

template<typename particlesSupport_type, typename particlesDomain_type, typename VerletList_type, size_t NORMAL_ID = INT_MAX>
class PPInterpolation< particlesSupport_type, particlesDomain_type, VerletList_type, NORMAL_ID >

Class to perform particle to particle interpolation using DC-PSE kernels.

Template Parameters

particlesSupport_type	Type of the particle set from which to interpolate.
particlesDomain_type	Type of the particle set to which to interpolate.
VerletList_type	Type of the Verlet List of the particle support set (particlesSupport)
NORMAL_ID	Property ID for the normal field of the particle set.

Parameters

particlesFrom	Particle set from which to interpolate.
particlesTo	Particle set to which to interpolate.
ord	Convergence order of the numerical operator.
rCut	Size of the support/argument for cell list construction. It has to include sufficient enough particles to create the support.
isSurfaceInterpolation	If not passed as true, interpolation is performed on the bulk.
oversampling_factor	Multiplier to the minimum no. of particles required by the operator in support.
support_options	default:RADIUS (selects all particles inside rCut, overrides oversampling).

The interpolation is performed using the (Surface) DC-PSE operators corresponding to the zeroth order derivative. Inside the constructor, the differential signature vector is set to zero, and a Dcpse object is created. Interpolation is then performed when calling the p2p method passing the property ID of the two sets <prop_From,prop_To>.
