[TRNSYS-users] active layer energy balance

[Adriana Angelotti <Adriana.Angelotti@polimi.it>]

Dear trnsys users,

I have some troubles with active layers simulations.
By reducing the simulation time step from 1h to 10 min (but even 30 
min is ok) I've been able to remove some fluctuations in the outlet 
temperature of the fluid.
However, If I look at the detailed energy balance report for the 
active layer surfaces, I see that BAL_ENERGY_SURF is generally not 
zero (around 20W), even if no more
fluctuating. Should this be considered a problem? How can I fix it?
Thank you for any suggestions.

Adriana
