[Bldg-sim] EE4 crash - hydronic radiators in MURB - Help!

I could REALLY use some help troubleshooting my model.    Many thanks in advance!

I am trying to build an EE4 model of a MURB with hydronic (heating only) radiators off central boilers, with ventilation air ducted to each suite from outside, with no central make-up air unit.  The ventilation air is drawn in using scheduled operation of washroom exhaust fans.   I am modeling the system as 2-pipe fan coil, with zero fan power.

I have worked through the errors, and the simulation will start to run, then freezes and goes unresponsive.  I am able to generate the loads using the sizing function.  No DOE report is generated.  Actually when I try to open the (0 kb) DOE file, I get a D2SimViewer error "Out of memory."

I have been working through the modelling guide to try to determine what could be causing this, but I have not been able to fix the problem.

I am not an expert at EE4, so perhaps there is a model-building convention that I have disobeyed.

Any help would be appreciated!  I am getting a little desperate, and unfortunately need to model in EE4, as this is the only acceptable software for this project.

Kind Regards,
