Preliminary results of 1–D fully hydrodynamic numerical calculations including accretion and mass loss on a 1M⊙ hot white dwarf are presented. For the case of Ṁ = 10−8M⊙/yr and Teff = 125000°K we get flashes of duration of ∼ 30 – 40 yrs which reccur every ∼ 1500 years. During each flash ∼ 6x10−6M⊙ is lost (∼ 40% of the accreted envelope.
