inlinestatic

M2P or P2M for one particle.

Template Parameters

prp_g	property to interpolate from(M2P) or to(P2M) for grid
prp_v	property to interpolate to(M2P) or from(P2M) for vector
m2p_or_p2m	mesh to particle or mesh to particle interpolation

Parameters

it	iterator used to retrieve the particle p for interpolation
vd	vector of particles
domain	simulation domain
ip	index of the grid on each direction (1D) used for interpolation
gd	interpolation grid
dx	spacing on each direction
xp	Point that store the position of xp
a_int	coefficients on the stencil points
a	coefficients of the kernel for each direction, consider that for 3 dimensions the kernel is the multiplication the 1D kernel on each direction. The "a" array store the calculated coefficient of the 1D kernel on each direction
x	position of
sz	grid size
geo_cell	cell list to convert particle position into sub-domain id
offsets	array where are stored the linearized offset of the kernel stencil for each local grid (sub-domain)
