acoustotreams.ScalarSphericalWaveBasis.defaultdim

static ScalarSphericalWaveBasis.defaultdim(lmax, nmax=1)

Default number of modes for a given mulipolar order.

Given the maximal value of l return the size of the corresponding T-matrix. This is the inverse of defaultlmax(). A value of lmax=-1 is allowed.

Parameters:

• lmax (int) – Maximal multipolar order

• nmax (int, optional) – Number of particles, defaults to 1

Returns:

int
