Many practical problems, such as a solar panel, a microplate inside an electronic device, a thin layer of metal exposed to a laser, or the bending of a reinforced concrete slab, are described by various boundary value problems for the biharmonic equation. Solving biharmonic equations using iterative methods is extremely inconvenient due to the requirement to perform a large number of arithmetic operations, in addition, the number of iterations in which often turns out to be very large. The consideration of biharmonic equations with Dirichlet and Neumann boundary conditions limits the use of difference methods for their numerical solution. Therefore, the development of highly accurate and efficient direct numerical methods for solving such equations is of particular scientific interest. For this purpose, in this article, for the numerical solution of boundary value problems for the biharmonic equation, it is proposed to use a direct numerical method - a discrete version of the preliminary integration method with high accuracy and efficiency.
