Numerical solution of the Rayleigh equation in non-linear vibration is studied in this paper. The di erential equation is integrated on a particular interval (0; T p2 ) with the initial value condition, u = A i and du=dt = 0 at the time t = 0. The value T p2 is determined from the condition such tha

Abstract
The aim of this communication is to compare different algorithms for the solution of the 1โD nonโlinear heat equation. A standard finiteโelement method is implemented for the space discretization which transforms the initial problem into a nonโlinear ordinary differential system. This new system is then solved by means of seven classical algorithms included in the ACSL software (advanced continuous simulation language). Three test cases are considered, and results are compared with available analytical solutions.
