<font size=2 face="sans-serif">Jeff,</font><br><br><font size=2 face="sans-serif">It's great to hear from the creator
of the component! I have taken this wrong assumption because the mathematical
reference says that: </font><font size=2 face="Arial">"... For the
sake of simulation speed, the model breaks the ground along two axes of
symmetry (in the x and y directions) and simulates only one quarter of
the field, multiplying energy transfer results to arrive at the total effect."</font><br><font size=2 face="Arial">What I would like to simulate is something
like:</font><br><img src=cid:_1_26EC723C08F81210003D8F06C12581D7 width=1136 height=390><font size=2 face="Arial"> </font><br><font size=2 face="Arial">38 pipes of 55m length in the ground buried
on average 2.5m (centerline of middle row). All pipes are connected at
inlets and outlets with collectors, and the same mass flow rate is assumed.</font><br><font size=2 face="Arial">The HX is close to the building wall: 1.5m,
which is insulated from the outside. At the end I want also combine building
thermal simulation with the 997 type in simulation studio, but I dont'
have building geometry yet. </font><br><font size=2 face="Arial">The shift in the middle row can be neglected
if the tool is not capable of including that. </font><br><font size=2 face="Arial">My goal is to simulate 25 years of HX and
get outlet temperatures and ground temperatures. I read that there's GroundTemperatureViewer
tool capable to see the .soil file, but it cannot find it yet. </font><br><br><font size=2 face="sans-serif">Best regards,</font><br><font size=3 color=#5f5f5f face="Calibri Light"><b>Jakub Winiarski</b><br>R&D Specialist / Energy Simulations </font><p><img src=cid:_2_08F7B65C08F7B3F0003D8F06C12581D7><br><font size=3 color=#5f5f5f face="Calibri Light">kom. +48 882 341 596<br>e-mail: </font><a href=mailto:b.starosielec@mostostal.waw.pl><font size=3 color=#0082bf face="Calibri Light"><u>j.winiarski@mostostal.waw.pl</u></font></a><p><font size=3 color=#002060 face="Calibri Light">mostostal.waw.pl</font><font size=3></font><br><img src=cid:_2_08F7C29408F7C028003D8F06C12581D7><font size=3 color=#002060 face="Calibri Light"><b>

<trnsys-users-bounces@lists.onebuilding.org></font><br><hr noshade><br><br><br><font size=3>Jakub,</font><p><font size=3>As the author of Type997, I can tell you that the model
most certainly does NOT use 1/4 symmetry. There's no way to apply
the symmetry as the fluid changes temperature along the entire length axis
and across the entire width and depth of the piping array. That's
why Type997 takes both the left and right, and both the front and back,
parameters (insulation extension, far-field boundary etc.). If it
was 1/4 symmetry it would need only one of front/back or left/right. Why
don't you send a sketch showing what you'd like to model and we can see
if 997 is the right model. We have other more generic models that
can handle a wider range of geometries.</font><p><font size=3> </font><p><font size=3>Jeff</font><p><font size=3> </font><p><tt><font size=3>---<br>Jeff Thornton<br>President - TESS LLC<br>22 N.

of domain is calculated. That is why the user can provide insulation on
all four bounding surfaces or none. If there is a way to 'turn off' the
