Hi Leadoc1996, will you expand on your question? |

I hope so. But now I have a new problem.My particle will run out of the boundary, and the calculation will stop. and do you have any idea what might have caused that |

This can be caused by a number of things. The best thing to do is to run the code in debug mode in Visual Studio. Double check your boundary conditions. You can also try reducing the courant number. |

Or does it have anything to do with my grid |

It's difficult to say without debugging the code. Have you tried that? It's something you'll have to learn to do to understand issues like this. From the image below, it does look like there is an "explosion" of MP's. It may be caused by the material parameters or the grid. Again, you must debug the code to find out. |

I want to know if the problem of using multi-core computing is solved in 2024 |

Unfortunately, it's not possible to understand what's going on with your model from a single Paraview image. You haven't said what you're trying to model, the features you're using, the model parameters, etc. Also, it appears that your model is very large in terms of number of material points. As is the case with any numerical model, I'd recommend with as simple and small of a model as possible then, only after understanding how you model behaves, adding size and complexity step by step and very slowly. |

I would like to know if parallel computing is supported |

@murphy-john So you compiled a version with OPENMP (Multiprocessing) and got too much different results from single-core processing? I did some research on the anura3d deepwiki (https://deepwiki.com/search/i-need-more-information-on-how_157ca0e5-0898-4017-9d5d-b9f347dd08c1?mode=deep ), and it seems we could implement the multiprocessing, although i think the issue on the difference in results may be given to the nature of the physics... I really would like to implement MP. |
