Detailed Description

template<unsigned DIM>
class NagaiHondaForce< DIM >

A force class for use in vertex-based simulations, based on a mechanical model proposed by T. Nagai and H. Honda ("A dynamic cell model for the formation of epithelial tissues", Philosophical Magazine Part B 81:699-719).

Each of the model parameter member variables are rescaled such that mDampingConstantNormal takes the default value 1, whereas Nagai and Honda (who denote the parameter by nu) take the value 0.01.
