Is there possible way to read functions in .vtu files


I’m wondering that can I read the functions in vtu file in legacy DOLFIN?

So I have ran some simulations, and I store the solution in vtu files, then I want to use the solution when I run some other simulations, can I obtain it by reading the vtu file?

Don’t think so, since vtu files were never intended for checkpointing.

Next time, you may want to use XDMFFile.write_checkpoint instead.
