N2 - We consider numerically unquantized Josephson vortices at asymmetric grain boundaries in YBCO films. The study is focused on the effect of random variations of facets size on the values of fractional flux carried by these vortices. The grain boundaries are treated as Josephson junctions with a critical current density alternating along the junctions with a typical length-scale of order of the facets size. Numerical simulations demonstrate that the value of the flux of the unquantized vortices varies along the junction depending on the local Josephson properties of the grain boundaries.
