  If the simulation begins to have problems at very high flow rates,
check to make sure that there is actually enough pipe volume in your
system to contain the amount of fluid that you are trying to pump. You
will probably have to decrease the time step, increase the size of the
bore field, perhaps add or increase the size of the pipes that lead
from the heat pump to the field, and perhaps increase the size of the
heat pump itself as well.<br>
Kind regards,<br>

  <p class="MsoNormal"><span lang="EN-US">Hi <br>
  <br>
I am trying to run an application in geothermal heat pump, with the
pre-installed module of the tess libraries (without the vertical tubes)
and I
have noticed the with high flow values (over 8000 kg/h) i have an error
"overflow stack". But generally i canot be sure if the results that i
get are correct, because i am very new to geothermal heat pumps.. <br>
  <br>
Could anyone help me with the error that I get, and suggest me a way to
run a
correct case ?<br>
  <br>
  <br>
  </span>thank you<o:p></o:p></p>
