  We conduct three-dimensional hydrodynamical simulations, and show that when a
secondary star launches jets while performing spiral-in motion into the
envelope of a giant star, the envelope is inflated, some mass is ejected by the
jets, and the common envelope phase is postponed. We simulate this grazing
envelope evolution (GEE) under the assumption that the secondary star accretes
mass from the envelope of the asymptotic giant branch (AGB) star and launches
jets. In these simulations we do not yet include the gravitational energy that
is released by the spiraling-in binary system. Neither do we include the
spinning of the envelope. Considering these omissions, we conclude that our
results support the idea that jets might play a crucial role in the common
envelope evolution, or in preventing it.
