Reading functions from hdf5file without saved mesh

Hi all, I saved some functions in a hdf5file and tried to read them back however I realised that I didn’t save mesh in the file. Is it still possible to read the functions? Will it work by providing a newly created mesh (but identical).

The PDEs were solved on a cluster and it took me a few days to get the results. I hope I don’t have to rerun them…

Thank you!
