acoustotreams.vfield

acoustotreams.vfield(r, *, basis, k0, material=AcousticMaterial(1.3, 343.0, 0.0), modetype=None)

Velocity field.

The resulting matrix maps the pressure field coefficients of the given basis to the velocity field in Cartesian coordinates.

The velocity field is given in units of \(\frac{1}{\rho c}p\).

Parameters:

• r (array-like) – Evaluation points

• basis (ScalarBasisSet) – Basis set.

• k0 (float) – Wave number.

• material (AcousticMaterial or tuple, optional) – Material parameters.

• modetype (str, optional) – Wave mode.
