Is it possible to `export_data` ?

[ateixeira0163]

I saw that in the bindings file, there's a commented method export_data that is present in the documentation of polyfempy.
I would like to know if this function would allow to save a simulation state that latter I could reuse importing this data and starting another simulation from it. I tried compiling just by un-commenting the function but it didn't work, is there a way to make it work and if it is supposed to work as I described?

Thanks!!
