Hello @Aaron_Kaplan,
I was trying to use pymatgen.io.validation for the layered structures calculated using optb86b-vdw. In reasons I received this error message:
['NO MATCHING MP INPUT SET --> no matching MP input set was found. If you believe this to be a mistake, please create a GitHub issue.']
Could you please give information what functionals are valid for the calculations including Van der Waals interactions?
Best,
Daviti
