Non-reflecting boundary conditions modification is described, allowing at modelling of infinite domain, all the waves that impinge on the finite computational domain’s boundary, going out freely, without spurious wave reflection. For this method usage all the requirements are formulated. It is shown, based on the example of striker penetration into 3D half-space, that described approach allows decreasing computational domain with accuracy saving.
