shamrock.external.coala.kernel_collision.func_kernel(kernel, K0, u, v)

Function to compute kernels at u and v

Parameters

kernelscalar, type -> integer

select the collisional kernel function

K0scalar, type -> float

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

uscalar, type -> float

mass variable (colliding grain of mass u)

vscalar, type -> float

mass variable (colliding grain of mass v)

Returns

resscalar, type -> float

evaluate kernel at u and v
