<span style='font-family:Verdana'><span style='font-size:12px'>Hello,<br />
<br />
Usually, when using the assistant to create a multizone building, the convection coefficient between the soil and the floor is set to 999 to reproduce the absence of thermal resistance.<br />
<br />
But when I create a file using the Trnsys3D import from Sketchup, this same coefficient is set by default to 0,001.<br />
Why is that ?<br />
<br />
Please help me understand</span></span>
