<p>Yossef,</p>
<p> I am not familiar with Mathis and have used TRNFlow only a
little. I have, however, used Type97 quite a lot for air flow
modeling. Type97 provides a link between Trnsys and an airflow
modeling tool called CONTAM. There is a slight disadvantage in
that the building has to be defined both in both TRNSYS and in
CONTAM. However, the transparency and the flexibility of the link
make it worth it. Type97 (and its expanded version Type98) are
both part of the standard Trnsys18 library.</p>
<p>kind regards,</p>
<p> David</p>

<div>Hi,</div>
<div><br>
</div>
<div>we want to buy an airflow modelling tool for trnsys but we
hesitate between TRNFLOW and type 159 Mathis-TRNSYS. Could you
please advise us about this, especially which is the easiest
one to use.<br>
