v0.5.2

v0.5.2 Release Notes

pydpf-core 0.5.2 release for Ansys 2022 R2

What's Changed

Enhancements

• Three server configurations are available. PyDPF can communicate either in Process or via gRPC with DPF C++ core server.

  • InProcessServer: Loads DPF's binaries in Process and shares memory with DPF's data. Performance is greatly improved. Now the default configuration.
  • GrpcServer: Uses gRPC communication through DPF gRPC CLayer Ans.Dpf.GrpcClient.
  • LegacyGrpcServer: Uses gRPC communication through the Python module ansys.grpc.dpf.

• Enhanced DPF capabilities by creating custom Python operators. See the Create Custom Operators documentation.

• You can now use RuntimeClientConfig (commit) and RuntimeCoreConfig to parametrize DPF.
  RuntimeClientConfig (commit) allows you to:

  • Set the streaming_buffer_size while streaming data through gRPC server configurations.
  • Choose whether to stream float or double values while streaming Field data through gRPC server configurations.
  • Choose whether to return numpy arrays by default (for scoping's IDs, field's data_pointer). The default is now True.

  RuntimeCoreConfig allows you to set the number of threads used (on the server side) for operators that enable multi-threaded data computation.

• Parallelized pre- and post-processing workflows with remote operators.

• Added new operators in the ansys.dpf.core.operators module, such as logic.ascending_sort(), logic.ascending_sort_fc(), logic.descending_sort(), logic.descending_sort_fc(), serialization.data_tree_to_json(), serialization.json_to_data_tree(), mesh.meshes_provider(), and so on. See the PyDPF documentation related to operators to learn how to use them.

• Warped mesh in plotter: Enable data visualization on a deformed mesh. Example here.

Continuous Integration

• ansys-dpf-gate is a new dependency of ansys-dpf-core.
• tqdm replaces progressbar2 as the third party module for progress bars.
• Backward compatibility workflow running on Ansys 2022 R1.
• Examples workflow running documentation examples for different server configurations.
• protobuf breaking change is not supported, supported versions are <=3.20.1.
• Added Dependabot to CI.
• Added dependency on packaging module.

Bug fixes

• Fixed circular references between DPF objects.

Documentation fixes

• Improved user guide. Added section on custom operators, usage of DPF XML file, documentation on main entities, and DPF concepts.
• New example: ASME Section VIII Division 2: pressure vessels, by @jviqueg
• Automatically generate Graphviz diagrams in documentation examples.
