Abstract: The invention notably relates to a computer-implemented method for designing a physical system constrained by a system of equations involving variables, the method comprising the steps of partitioning the variables involved in the equations into fixed variables and unfixed variables, thereby setting the system to a restricted system with a degree of freedom equal to 1, computing a parameterized curve of solutions of the restricted system in the domain of the unfixed variables, for at least one pair of unfixed variables, displaying the projection of the curve in the product of the domains of the pair, and navigating the solutions on the parameterized curve and representing, real-time, the current navigation position on the projection of the curve. Such a method improves the design of a physical system constrained by equations involving variables.
