For example,ĭefines a surface named warm_surface. The namelist group that defines the types of boundary conditions is SURF. This chapter describes how to specify the properties of the bounding surfaces of the flow domain. This chapter covers RAMP (time dependent) namelist group, too.ĭefining boundary conditions, SURF It is your responsibility to supply the thermal properties of the materials, and then assess the performance of the model to ensure that the phenomena of interest are being captured. Second, even if all the material properties are known to some degree, the physical phenomena of interest may not be simulated properly due to limitations in the model algorithms or resolution of the numerical mesh. This is the most challenging part of setting up the simulation: first, for both real and simulated fires, the growth of the fire is very sensitive to the thermal properties of the surrounding materials. Third, some properties are set up, as the types of boundary conditions (SURF). 1.4.5 Dynamic pressure at an open boundaryīoundary conditions.
