<P DIR=LTR><SPAN LANG="nl"><FONT SIZE=2 FACE="Courier New">I need help with TRNSFLOW. To begin, for some reason the example that </FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="nl"><FONT SIZE=2 FACE="Courier New">has the program has some mistake and I would like that you were </FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="nl"><FONT SIZE=2 FACE="Courier New">sending yours this one and if you can someone more in order that I was </FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="nl"><FONT SIZE=2 FACE="Courier New">helping myself.</FONT></SPAN></P>
<BR>
<P DIR=LTR><SPAN LANG="nl"><FONT SIZE=2 FACE="Courier New">I have started creating a simple example, after reading the manuals, </FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="nl"><FONT SIZE=2 FACE="Courier New">but I have problems to do a coherent net.</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="nl"><FONT SIZE=2 FACE="Courier New">Only I want to take advantage of the air of the face North of a </FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="nl"><FONT SIZE=2 FACE="Courier New">building to cool that of the face South.</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="nl"><FONT SIZE=2 FACE="Courier New">The net that I have created consists in:</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="nl"><FONT SIZE=2 FACE="Courier New">External Node + Crack + Thermal zone A + Crack + Thermal zone B + </FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="nl"><FONT SIZE=2 FACE="Courier New">Crack + External Node....</FONT></SPAN></P>

<P DIR=LTR><SPAN LANG="nl"><FONT SIZE=2 FACE="Courier New">In a beginning what I do is to simulate without defining the air net </FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="nl"><FONT SIZE=2 FACE="Courier New">and seeing the values of the temperatures in the zones. And later I </FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="nl"><FONT SIZE=2 FACE="Courier New">realize this net of air flow and observe that there are no variations. </FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="nl"><FONT SIZE=2 FACE="Courier New">That I am doing badly?. Thank you very much</FONT></SPAN></P>
