  We have developed the 2.5D version of the basic physically motivated 1D model
of Czerny & Hryniewicz (2011), i.e. Failed Radiatively Accelerated Dusty
Outflow (FRADO) model. This model is based on the idea that radiation pressure
acting on dust is responsible for the formation of the low ionized part of the
Broad Line Region (BLR). Such radiation pressure is strong enough to form a
fast outflow from the disk surface in the inner part of low ionized BLR. The
outflow properties depend on the basic physical parameters, like black hole
mass, Eddington ratio and gas metallicity. We here aim at estimating the disk
mass loss rate due to this process, and comparing the results with outflows
detected in Broad Absorption Line (BAL) quasars.
