Alternatively, this can be done with a concept in C++20. But implementing negative constraints is hardly feasible. Is the algorithm meant to be interchangeable? If whether `InteractionDynamics` or `InteractionWithUpdate` cannot/shouldn't...

I simplified the detection idiom with its simpler version here https://github.com/Xiangyu-Hu/SPHinXsys/pull/157 Now though, it must be added in all of them and would need to be modified for every new...

It is as per request from @Xiangyu-Hu who needs to have a smaller footprint on the CI disk consumption. A description has been briefly added. I leave it the rest...

The MacOS GitHub runner image is different between the build job and the test job. [20230921.1](https://github.com/actions/runner-images/blob/releases/macOS-12/20230921/images/macos/macos-12-Readme.md) [20231115.2](https://github.com/actions/runner-images/blob/macOS-12/20231115.2/images/macos/macos-12-Readme.md) The more recent version has Python 3.12, while the older is on 3.11,...

I assume close to nil. Previous version was creating an `affinity_partitioner` for each translation unit which is pretty close to this. This may have had an impact when the `affinity...

> is the building in CI parallelized? It seems that this is at least not explicit. Ninja build system does it in parallel by default. > Some tests are two...
