[20231213.zip](https://discourse.paraview.org/uploads/short-url/oxhkZrFTsMJULAiA1cy9ZxPsokS.zip) (1.3 MB)Hello, I generated a set of files for XMF and hdf5 after running my code, but I couldn’t run them in Paraview. Therefore, I have reviewed some answers related to my question here, but they still haven’t solved my problem. In addition, I am a new coder, can you help me solve this problem, or is there any problem with my file format. I will be very grateful! I have uploaded all my files, including the Xdmf.dtd file I downloaded.

Looks like your data is not correctly formated, you need to fix your data generation system.
