<p class="MsoNormal"><span style="font-family:"Comic Sans MS";color:#0070C0">I'm simulating a thermal active layer installed in the vertical external wall of a building using Type 399 connected to Type 56</span><o:p></o:p></p>

<p class="MsoNormal"><span style="font-family:"Comic Sans MS";color:#0070C0">As a first step, I connect Type 399 only to one facade by considering that the active layer occupied only 4 m² of the wall while the total area of this wall is 48 m²</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-family:"Comic Sans MS";color:#0070C0"> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-family:"Comic Sans MS";color:#0070C0">I include in the TRNBuild file of the building a new layer "HIGH_RESISTANCE" that have the same area of the portion of the facade where the active layer is installed (4 m²) in which
I define the energy gain on side 1 and side 2 that come (outputs) from Type 399</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-family:"Comic Sans MS";color:#0070C0"> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-family:"Comic Sans MS";color:#0070C0">The wall have 6 layers and the active layer is in layer no 4 and i use 4 discretization for each layer and the total mass flow is 60 kg/hr</span><o:p></o:p></p>

<p class="MsoNormal"><span style="font-family:"Comic Sans MS";color:#0070C0">I look in the description of Type 399, I didn't find nothing about the massflow and its relation with the discretization</span><o:p></o:p></p>
