I'm curious why `mesh` isn't enough? If you are given a surface in the format of a triangulation, then isn't that exactly what `mesh` is for?

+1 --- I've run into the same problem and my MWE is almost identical to the one above. For me this is a huge problem, because I am hoping to...

Thanks for the reply. Re 1) sounds great if possible. @hjchen1983 : you looked at the code before: would it really be easier to implement plane waves in this framework...

An initial interface between JuLIP and QuantumLab with minimal functionality; say energy and forces; should be straightforward. Once I have some functionality for molecules in JuLIP I'll come back to...
