osaft.core.functions.cartesian_2_spherical_vector(v_x, v_z, theta)[source]#

Transforms velocities in the a Spherical coordinate system (v_r, v_theta) of an axisymmetric model to the Cartesian system (v_x, v_z). See here for the definition of the coordinate system.

Parameters:

  • v_x (float) – velocity in radial direction

  • v_z (float) – velocity in tangential direction

  • theta (float) – polar angle

Return type:

tuple[float, float]
