- Changes in Connecting:
- Now instead of specifying `connection_name` directly, `my_name` and `connect_to` are used for the call to `Connect`.
- The `CoSimIO::Info` that is returned from `Connect` now contains the `connection_name` that needs to be used in subsequent calls to _CoSimIO_.
- This change was done to make the connection more robust and to make the selection of primary/secondary partner clear. This is only used internally e.g. for who opens a port and who connects to it.
- Introduced `CoSimIO::ModelPart` for exchanging of meshes
- Simplified version of [`Kratos::ModelPart`](https://github.com/KratosMultiphysics/Kratos/blob/master/kratos/includes/model_part.h)
- Simplifies and unifies the usage of `Import-/ExportMesh`
- See the tutorials on how to use it:
- [C++](https://kratosmultiphysics.github.io/CoSimIO/model_part/model_part_cpp.html)
- [C](https://kratosmultiphysics.github.io/CoSimIO/model_part/model_part_c.html)
- [Python](https://kratosmultiphysics.github.io/CoSimIO/model_part/model_part_python.html)
- FileCommunication:
- By default now done in folder. This way leftovers from previous simulations can be easily deleted (done automatically).
- working directory can be specified
- stability of initial connection was significantly improved.
- Python interface: Data is no longer copied when going from Python to C++ and vice versa.
- `Import-/ExportData` now uses `CoSimIO::DoubleVector` (small wrapper around [`std::vector`](https://en.cppreference.com/w/cpp/container/vector))
- `Import-/ExportMesh` now uses `CoSimIO::ModelPart`
- Continuous Integration:
- Adding Python 3.9 (now has Python v3.5 - v3.9)
- Adding CentOS 7 build with GCC 4.8.5
- Enforcing C89 standard
- Many improvements and cleanups under the hood
