Summary: The dam’s construction schedule has significant influences in long-term concrete temperature, whose variations may produce local thermal stress and thus result in damage and cracking. This paper describes a methodology for predicting the thermal evolution in large concrete placements with special emphasis on gravity dams during their construction by the Boundary Face Method (BFM). A simulation tool that completely integrated into a CAD environment (here UGNX is adopted) has been developed. Benchmark examples are presented and compared with other solutions by the FEM.
