making Material and MultiMaterial objects JSON serializable
Closed this issue · 1 comments

When using different materials in parameter studies it is useful to be able to dump the Material or MultiMaterial to a json file which means they must be JSON serializable.
This does not currently work
import json
from neutronics_material_maker import Materail
a = Material('H2O',temperature_in_C=30, pressure_in_Pa=101325)
json.dumps(a)
I think this is due to the a.dict including the openmc_material object that does not look JSON serializable.
We should be able to overwrite the methods that convert this into a JSON dictionary so that it skips the ones that don't work and skips the ones starting with _
Currently a.__dict__ outputs
