Maximum size of compartment

[Larry Dewberry]

I have an application where the building dimensions exceeds 100 m.  I am breaking it up into compartments less than 100 m max, but the location x or y has to be more than 100 m to lay it out.  The simulation runs and finishes and gives results that look right, but gives an error message about the size.  Any reason to beleive the results are incorrect?  The simulation will not run if the compartment dimensions exceed 100 m.

The limitations are arbitrary limits intended to flag the calculation
as outside typical limits. There are validation tests where the model
does quite well with compartments as large as 20 000 m^3. Still, as
you have done, such large-scale calculations should be reviewed for
reasonableness of the results. It's more a function of the relative
size of the fire to the compartment; very small fires in very large
compartments or very large fires in very small compartments test the
limits of the model far more that just large compartments with a fire
typical for the compartment size.
