  • Abstract A Weighted Essentially Non-Oscillatory (WENO) reconstruction tech-
    nique is developed that converts cell-averages on one grid to another grid
    to high order. Since we can not combine two linear polynomials with linear
    weights to obtain the third order accuracy, we take the whole computation to
    its primitive level. We de ne an integral base CWENO3 scheme that com-
    bines two primitive functions of the linear polynomials to obtain third order
    accuracy. The new scheme uses a compact stencil of three cell-averages, and
    weight functions are used. Numerical results show that this scheme is third
    order accurate for smooth problems and gives good results for non-smooth
    problems.
