N2 - In this study, we consider cosmological models driven by several canonical or noncanonical scalar fields, and we show the manner in which twinlike models for a canonical model can be constructed from noncanonical ones using the superpotential method. We conclude that it is possible to construct twinlike models for multifield cosmological models, even with a nonzero spatial curvature. This work extends the discussions of [D. Bazeia, and J. D. Dantas, Phys. Rev. D 85, 067303 (2012)] to cases with multi scalar fields and with non-vanished spatial curvature, by using a different superpotential method.
