Function to precompute array depending only on massgrid to evaluate the coagulation flux DG scheme with piecewise constant approximation Numba formalism

Parameters

kernelscalar, type -> integer

select the collisional kernel function

K0scalar, type -> float

constant value of the kernel function (used to adapt to code unit)

Qscalar, type -> integer

number of points for Gauss-Legendre quadrature

vecnodes1D array (dim = Q), type -> float

nodes of the Legendre polynomials

vecweights1D array (dim = Q), type -> float

weights coefficients for the Gauss-Legendre polynomials

nbinsscalar, type -> integer
