Limitations No 3D time-dependent k-epsilon turbulence
solvers (3D airflow around buildings) yet

Integrated HAM Modeling & Simulation
Drawbacks
(1) basic knowledge of Matlab required
(2) HAMLab is research tool. No user-friendly interfaces and user guides.
(3) simulation of FEM based integrated models can easily become very computation time consuming.
Introduction Modeling Examples Practical Application New developments Conclusion
Integrated HAM Modeling & Simulation
Benefits it takes advantage of maintained
Matlab/SimuLink and FemLab all presented HAMLab models in this paper
are public domain; it is relative easy to integrate new models
that are based on ODEs and/or PDEs. the simulation facilitates open source
modeling if desired, models can be compiled into stand-
alone applications
