We investigate aspects of universality in the two-dimensional (2D) spin-1 Baxter- Wu model in a crystal field ∆ using a parallel version of the multicanonical algorithm employed at constant temperature T . A detailed finite-size scaling analysis in the continuous regime of the ∆ − T phase diagram of the model indicates that the transition belongs to the universality class of the 4-state Potts model. The presence of first-order-like finite-size effects that become more pronounced as one approaches the pentacritical point of the model is highlighted and discussed.
