In this paper a fourth‐order variable coefficient parabolic partial differential equation, that governs the behaviour of a vibrating beam, is solved by using a three level method based on non‐polynomial quintic spline in space and finite difference discretization in time. We also obtain two new high accuracy schemes of O ( k 4 , h 6 ) and O ( k 4 , h 8 ) and two new schemes which are analogues of Jain's formula for the non‐homogeneous case.
