3.Conclusions

•HamLab is evaluated as solver for HAM problems based on partial differential equations (PDEs) & ordinary differential equations (ODEs).

•Examples of typical integrated HAM modeling problems such as dynamic airflow and heat transport in combination with a room model and controller are relatively easy to model.

•The simulation results of the presented models show a good agreement with measurements.

•The HamLab simulation environment requires Matlab, SimuLink & FemLab and is a powerful and flexible environment for modeling and solving HAM problems.

3.Conclusions

Benefits: •The wide application area. The software is designed to simulate systems of coupled PDEs, 1D, 2D or 3D, non-linear and time dependent. •There is a clear relation between the mathematical model and (compact) program code in terms of specified PDE coefficients and boundary conditions.•The easy-to-use default gridders and solvers give accurate solutions.•The graphical output capabilities.

Drawback:•MatLab, SimuLink and FemLab are required to use HamLab
