  We consider cosmological models driven by several canonical or noncanonical
scalar fields. We show how the superpotential method enables one to construct
twinlike models for a particular canonical model from some noncanonical ones.
We conclude that it is possible to construct twinlike models for multi-field
cosmological models, even when the spatial curvature is nonzero. This work
extends the discussions of [D. Bazeia and J. D. Dantas, Phys. Rev. D, 85 (2012)
067303] to cases with multi scalar fields and with non-vanished spatial
curvature, by using a different superpotential method.
