for single focal point, use handybeam.solve_singlepoint_py()

Contains excitation solvers.

A basic single-point-focus excitation solver is handybeam.solver.Solver.single_focus_solver()

class handybeam.solver.Solver(parent=None)[source]

” Contains the OpenCL subsystem for single focus solver.

This class calls the OpenCL wrapper for the single focus solver.


Initializes an instance of class Solver.

Parameters:parent (handybeam.world.World()) – This is an instance of the handybeam world class.

Return repr(self).


Return str(self).


changes the parent of an instance of the class Solver.

Parameters:new_parent (handybeam.world.World()) – This is an instance of the handybeam world class.
single_focus_solver(x_focus, y_focus, z_focus, local_work_size=(1, 1, 1), print_performance_feedback=False)[source]

Solve excitation coefficients for a single focal point

This method calls the OpenCL wrapper mixin class single_focus_solver which determines the set of activation coefficients required to produce a single focal point a given point in space.

  • x_focus (numpy float) – This is the x-coordinate of the requested focal point position.
  • y_focus (numpy float) – This is the y-coordinate of the requested focal point position.
  • z_focus (numpy float) – This is the z-coordinate of the requested focal point position.
  • local_work_size (tuple) – Tuple containing the local work sizes for the GPU.
  • print_performance_feedback (boolean) – Boolean value determining whether or not to output the GPU performance statistics.
