Comsol models created with comsol 5.5.0.359 and it will scream blue murder if you try to open them with a different version. All the data from the impedance meter (data/*/*.csv) has three columns: frequency / Hz, Impedance magnitude / Ω and Phase / °. The columns in data/comsol.csv are electrode distance / m, muscle thickness / m, hypodermis thickness / m, dermis thickness / m, epidermis thickness / m, stratum corneum thickness / m, frequency / Hz and complex impedance / Ω. The columns in data/comsol_wobble.csv are wobbliness (see model or paper for an explanation), frequency / Hz, complex impedance / Ω.
