Numerical grid adaptation method for finite volume methods is presented. Unlike traditional adaptation methods, the method presented moves vertices of control volumes instead of their centers. To perform such movement, geometric information is used generated for the control volume method. The presented method can be used for two- and three-dimensional grids of arbitrary structure. Possibilities and limitations of the grid adaptation method are shown by various examples
