-The \ct{Time Step} indicates the total number of iterations. The date and time indicate the current wall clock time. The \ct{STEP SIZE} indicates the size of the numerical time step. The \ct{Total Time} indicates the total simulation time calculated up to that point. The \ct{Pressure Iterations} are the number of iterations of the pressure solver for the corrector (second) half of the time step. The pressure solver iterations are designed to minimize the error in the normal component of velocity at solid walls or the interface of two meshes. The \ct{Maximum Velocity Error} indicates this error and in which grid cell it occurs.  \ct{Max/Min divergence} is the max/min value of the function $\nabla \cdot \bu$ and is used as a diagnostic when the flow is incompressible (i.e., no heating); \ct{Max CFL number} is the maximum value of the CFL number, the primary time step constraint; \ct{Max VN number} is the maximum value of the Von Neumann number, the secondary time step constraint. The \ct{No. of Lagrangian Particles} refers to the number of particles in the current mesh. The \ct{Radiation Loss to Boundaries} is the amount of energy that is being radiated to the boundaries. As compartments heat up, the energy lost to the boundaries can grow to be an appreciable fraction of the \ct{Total Heat Release Rate}.

 Following the completion of a successful run, a summary of the CPU usage per subroutine is listed in the file called \ct{CHID_cpu.csv} (Section~\ref{out:CPU}). This is useful in determining where most of the computational effort is being placed.
