<p>Mariam,</p>
<p> The wall transfer function coefficients are computed with a
certain time base. When you run a simulation in which your time
step is a lot smaller than the wall time base you start to see the
times at which the wall transfer function coefficients are
updated, which produces this step-like plot. Depending on the
construction of the walls in your building, you can probably
reduce the wall timebase and get rid of the steps. The time base
is set in TRNBuild's output manager. I'd suggest using a 0.25h
time base.</p>
<p>kind regards,</p>
<p> David</p>

I am simulating a 3-floor building to observe the change in
