Newtonian equations of motion

The generalized Newtonian equations of motion governing the dynamic fish model take the form of a set of coupled second-order ordinary differential equations:

is the net internal force on node i due to the viscoelastic units connecting it to nodes tex2html_wrap_inline2410 , where tex2html_wrap_inline2412 is the index set of neighboring nodes. Finally, tex2html_wrap_inline2414 is the external (hydrodynamic) force on node i.
