Integrated HAM Modeling & Simulation

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.

Introduction

• Modeling Examples

• Practical Application

• New developments

(31)

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.

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
