Abstract
The classical 3D discrete frustrated phi (4) (DIFFOUR) model is studied wit h Monte Carlo techniques. The phase diagram is topologically identical with that calculated in mean-field approximation, but the transition temperatur es are different. This allows a comparison with experimental phase diagrams .
