<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Dear All,
<div><br>
</div>
<div>I have a problem with TYPE 80. I would like to see the <i>convective coefficient</i> <i>for</i> <b>back side</b> of surface change in time. </div>
<div><span style="font-size: 10pt;"><br>
</span></div>
<div><span style="font-size: 10pt;">I tried to set TYPE 80, I started in TRNBuild and I chose the INPUT <i>keyword </i>, HBACK3, then in Simulation studio I connected TYPE 80 <i>Convective coefficient for back side of surface </i>with TYPE 56 HBACK3, and them
I plot it.</span></div>
<div><span style="font-size: 10pt;"><br>
</span></div>
<div><span style="font-size: 10pt;">When I run the simulation the convective coefficientfor <b>back side</b> starts from 0 and it remains always constant at a about 9.5. I done the same thing with VERTICAL and the result does not change.</span></div>
<div><span style="font-size: 10pt;"><br>
</span></div>
<div>I can set the <i style="font-size: 10pt;">convective coefficient</i><span style="font-size: 10pt;"> </span><i style="font-size: 10pt;">for</i><span style="font-size: 10pt;"> </span><b style="font-size: 10pt;">front side </b><span style="font-size: 10pt;">of
surface with TRNBuild chosing internal calculation.</span></div>
<div><span style="font-size: 10pt;"><br>
</span></div>
<div><span style="font-size: 10pt;">Questions:</span></div>
<div><span style="font-size: 10pt;"><br>
</span></div>
<div><span style="font-size: 10pt;">-someone could explain me how to use INPUT especially the difference between HBACK3 and VERTICAL.</span></div>
<div><span style="font-size: 10pt;"><br>
</span></div>
<div><span style="font-size: 10pt;">-how select a proper surface, for instance I would like to see the convective coefficient for the surface facing to the south, for the surface facing to the north and so on.</span></div>
<div><span style="font-size: 10pt;"><br>
</span></div>
<div><span style="font-size: 10pt;">Regards</span></div>
