Several simulations of the L‐regimes of ASDEX Upgrade edge plasma have been performed with the B2 SOLP S5.0 2D fluid transport code for a wide range of parameters. A conclusion has been made that the radial electric field in the separatrix vicinity is close to the neoclassical value. The poloidal $ \vec E \times \vec B $ drifts and compensating parallel fluxes in the scrape‐off layer are larger in the H‐mode due to steeper gradients while the qualitative pattern of the flows is similar to that of the L‐mode.
