The TRNSYS result (*.lst and *.log) files should show you more
information on the cause of the error. However, if I had to guess about
it, I would first check and make sure that the mass flow rate that goes
to your active layer (as an input to Type56) is always either 0 or
about 10% above the 750 kg/h that TRNBuild calculates as the required
minimum value. The additional 10% is a bit of a mystery to me. I have
run across it quite a few times and I think it might have something to
do with issues of the density of the active layer liquid changing with
temperature. If keeping the flow rate higher does not work then in your
active layer specification, try setting the "minimum desired inlet mass
flow rate" to 10 (the default) instead of 5 and again make sure that
whenever there is flow going to though the floor, it is above 1500 kg/h.<br>
Kind regards,<br>
