A temperature transforming model was proposed to convert the enthalpy-based energy equation into a nonlinear equation with a single dependent variable. The model and the numerical scheme were first tested with diffusive phase-change problems. The model eliminates the time step and grid size limitations and is insensitive to the phase-change temperature ranges, proving that the model is flexible and can handle multi-dimensional phase-change problems which have large specific heat and thermal conductivity differences between the liquid and solid phases in a fixed grid system.
