Abstract Higher-order difference schemes always cause oscillation in convection calculation though they require much effort in the calculation. Overshoot and undershoot of the oscillation is troublesome particularly in the calculations of temperature, energy, and turbulence parameters. Filtering techniques improve both accuracy and stability, and some of them can completely suppress the overshoot or undershoot, when they are combined with the higher-order difference schemes. In the present study, a new min-max truncation (MMT) method is proposed. It is evaluated in two test problems of pure convection, and compared with other filtered and not-filtered difference schemes.
