+
+------------------
+
+### Test case
+
+UMD-SBI: Flame spread experiments in a 1.46 m corner wall configuration with MaCFP PMMA (based on the Single Burning Item (SBI) Test, EN13823)
+
+------------------
+
+### CFD package
+
+Code: Fire Dynamics Simulator (FDS)
+
+Version: 6.7.9-0
+
+------------------
+
+### Resolution
+
+#### Computational domain discretization (flow solver)
+
+Domain: 2.12 m by 2.12 m by 2.86 m (includes hood)
+
+Cell size: 2.5 cm and 1 cm for UMD props, 2.5 cm for DBI props.
+
+Cell type: Cubes
+
+Total cells: 2.39E6 (1 cm for the fire domain and 2cm for the rest), 1.4E6 (2_5 cm for the entire domain)
+
+#### Angular space discretization (radiation solver)
+
+Number of solid angles: 300
+
+------------------
+
+### Initial conditions
+
+Comments: Ambient temperature of 20 °C.
+
+------------------
+
+### Boundary conditions
+
+Comments: Between bottom edge of curtain and floor there was Open boundaries. The floor, hood cone, and hood curtains were solid. The top of the hood was a fixed volume flow exhuast of 0.56 m^3/s.
+
+------------------
+
+### Models (include parameters)
+
+Turbulence model: Default Deardorff turbulence model with FDS defaults of 0.5 for both Schmidt and Prandtl numbers.
+
+Combustion model: 1-step mixing-controlled reactions of propane (burner) and MMA (pyrolyzate)
+
+Radiation model: Finite-volume, gray gas with specified radiative fraction
+
+Radiative fraction: 0.35
+Yields: Soot: 0.018, CO_Yield 0.007.
+
+------------------
+
+### Pyrolysis Models (include parameters)
+
+Solver: FDS
+
+Radiation absorption model: 2-flux model in PMMA solid when an absoprtion coeffiicent is specified
+
+Material property set: Properties of black PMMA taken from the various json files at https://github.com/MaCFP/matl-db/tree/master/PMMA/Material_Properties.  
+
+Comments:
+
+
+------------------
+
+### Discretization methods
+
+Time: Second-order accurate Runge-Kutta
+
+CFL: 1
+
+Advection: Superbee flux limiter
+
+Diffusion: Second-order central difference
+
+Pressure-velocity coupling: Low Mach number approximation
+
+------------------
+
+### Computational Cost (hh:mm:ss)
+
+Wall clock time:  1 cm (667,229.941 s ) 
+
+Simulation time: 200 s 
+
+Number of CPUs (MPI Processes): 2.5 cm (6), 1 cm (6); 
+
+CPU cost (Number of CPUs * Wall clock time / Simulation time / Total cells): 1 cm (0.044 s); 
+
+------------------
+
+### Averaging period
+
+0.2 s
+
+------------------
+
+### Special issues/problems
+
+The simulation results including HRR are grid independent based on the two mesh sizes considered.
