Parameter sensitivity in nonlinear transient thermal problems. A general problem of parameter sensitivity of non-linear transient thermal systems is considered. The non-linear sensitivity path is followed by a weighted residual method employing the continuum description. The resulting finite element equations are derived. Both the direct differentiation and adjoint system methods are employed to evaluate sensitivity functional increments during the integration time step.
Numerical results illustrate the method proposed.
A. Radomski and O. Gajl . The complexity of the physical engineering objects requires new technologies in software development able to simulate real-life cases. The huge number of such cases can be covered by object-oriented paradigm. The system is an expert type program equipped with advanced monitoring and visualisation functions for existing dams. The software development process starting from the requirement description is presented.
