floating point exception

I want to perform an analysis of air recirculation and determine the percentage of dirty air that enters the intake duct (forcing fan system, 2 ducts) instead of exiting through the exhaust fan (green box). In this context, I encountered an error stating "floating point exception" (FIG. 2) and I suspect that there is a mistake in defining my boundary conditions (inlet, outlet, interior, wall). The boundary condition definitions I have made can be seen on FIG.1.
Can someone help me and tell me what I need to do so that I can run the calculation without any issues?
