Bempp-cl 0.4.1 [missing files - do not use]

  • Fix missing cl files in release

Bempp-cl 0.4.0 [missing files - do not use]

  • Updated FEniCSx interface to correctly orient normals so they all point outwards
  • Renamed Python library from bempp to bempp_cl

Bempp-cl 0.3.2

  • Updated FEniCSx interface to work with the upcoming release 0.9
  • Updated to work with up-to-date versions of Numpy, Scipy and Numba
  • BB spaces on open geometries

Bempp-cl 0.3.1

  • Corrected plotting of vector-valued elements
  • Updated FEniCSx interface to work with both main branch and version 0.6.0
  • Various bugfixes

Bempp-cl 0.3.0

  • Added ORSC operators for Helmholtz
  • Added MtE Pade operator
  • Added ORSC preconditioned Burton-Miller example
  • Updated FEniCSx interface to be compatible with newer versions
  • Various bugfixes

Bempp-cl 0.2.4

A number of bugfixes.

Bempp-cl 0.2.3

Added FEM-BEM coupling with DOLFINx. Added to_sparse and to_dense methods to discrete operators.

This version is linked to the Bempp-cl JOSS paper.

Bempp-cl 0.2.2

Assembly using the "novec" mode does not crash anymore.

Bempp-cl 0.2.1

Small patch release with the following fixes:

  • A proper error message is now given if Exafmm is not available.
  • Numba now does not produce an error message in single-precision.
  • Fixed the issue that evaluation points had to be handed over as the correct data type to Bempp.
  • VTK Export now does not produce errors
  • The Maxwell dieelectric notebook was updated for Bempp-cl 0.2

Bempp-cl 0.2.0

This release contains a number of major improvements:

  • In addition to OpenCL all operators are now also implemented in Numba, allowing Bempp to be run on systems without OpenCL stack. However, OpenCL is preferrable due to its better performance.
  • Internally, the exact implementation of operators has been fully abstracted out so that it is straight forward to write other compute backends (e.g. Cuda, Sycl, etc.)
  • All integral operators and potentials can now be assembled via FMM via interfaces to the Exafmm-t library (https://github.com/exafmm/exafmm-t).
  • Decorators for grid function callables have been worked over so that it is easy to disable Just-In-Time compilation. Alternatively, a vectorised of grid function callables is now possible.
  • The FEniCS interface now allows to obtain trace matrices for Nedelec function spaces for Maxwell FEM/BEM problems.
  • Bempp-cl now has automatic deployment with generation of Docker images and a fully automated testing infrastructure.
  • Many smaller bug fixes and performance improvements.

Bempp-cl 0.1.1

  • Export now works with meshio version 4
  • P1 spaces are correctly generated for open domains if include_boundary_dofs=False

Bempp-cl 0.1.0

  • First release of Bempp-cl
