Annotation We present the approach for computer simulation of magnetic field in a gap between two cylindrical permanent magnets connected by a yoke using FlexPDE software. Proposed approach shows that this implementation allows using program code written "almost natural mathematical language" for successful simulation in practical goals of physical experiments. Particularly, the provided program code and idea of introduction of an effective backsides curvature of magnets have been used in the series of acoustomagnetic studies, i.e. this publication serves also as an example of "reproducible calculations" ideology providing all actual computational details and code.
