Conclusion


Limitations No 3D time-dependent k-epsilon turbulence

solvers (3D airflow around buildings) yet

full 3D integrated HAM model => the simulation duration time ?

radiation (recently available in FemLab) not included in this research.



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.



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
