Module Contents¶

bempp_cl.api.operators.boundary.maxwell.electric_field(domain, range_, dual_to_range, wavenumber, parameters=None, assembler='default_nonlocal', device_interface=None, precision=None)¶: Assemble the electric field boundary operator.

bempp_cl.api.operators.boundary.maxwell.magnetic_field(domain, range_, dual_to_range, wavenumber, parameters=None, assembler='default_nonlocal', device_interface=None, precision=None)¶: Assemble the magnetic field boundary operator.

bempp_cl.api.operators.boundary.maxwell.multitrace_operator(grid, wavenumber, epsilon_r=1, mu_r=1, target=None, space_type='magnetic_dual', parameters=None, assembler='default_nonlocal', device_interface=None, precision=None)¶

Simplified version of multitrace operator assembly.

Parameters¶

gridGrid: Bempp grid object.
wavenumbercomplex: A real or complex wavenumber
epsilon_rfloat: Relative permittivity with respect to vacuum.
mu_rfloat: Relative permeability with respect to vacuum.
targetGrid: The grid for the range spaces. If target is None then target is set to the input grid (that is the domain grid).
space_typestring: One of “all_rwg”, “all_bc”, “magnetic_dual” (default), “electric_dual”. These lead to the following choices of space, range, and dual_to_range: default - (RWG, RWG), (BC, BC), (SNC, SNC) all_dual - (BC, BC), (RWG, RWG), (RBC, RBC) magnetic_dual - (RWG, BC), (RWG, BC), (RBC, SNC) electric_dual - (BC, RWG), (BC, RWG), (SNC, RBC)
parametersParameters: An optional parameters object.
assemblerstring: The assembler type.
device_interfaceDeviceInterface: The device interface object to be used.
precisionstring: Either “single” or “double” for single or double precision mode.

Output¶

The Maxwell multitrace operator of the form [[M, E], [-E, M]], where M represens the magnetic and E the electric field boundary operators in the respective spaces defined through space_type. Note that the operators in the first and second row have different discretisations depending on the type of spaces used.
