Reparameterize pearl_necklace (Trac #677) #303

Open butlerpd opened 5 years ago

butlerpd commented 5 years ago

Currently the parameterization of this models requires the following constraint in the fitting which may do funky things when using polydispersity:

constraint: string_thickness < radius

Not sure how best to handle. Could define string thickness as a percentage of radius as a multiple of string thickness but neither of those feel natural
