I would appreciate your help with the following questions!
I am reproducing an open source project on gihub( sukjulian/segnn-hemodynamics: Implementation accompanying our FIMH 2023 paper (github.com)) and the author declares to open its hdf5 dataset with paraview. This is a dataset obtained from CFD simulation, when I open it with paraview, the software only gives two readers, i.e. Visit Chombo Reader and Visit Tetrad Reader. theoretically this dataset belongs to Chombo, but I tried both and the software reports errors, among which the chombo The errors are reported as follows:
