abstract
The thermal effects of a localized fire bellow a concrete slab with the length of 10 m and
the thickness of 30 cm is simulated. The nonlinear equation of heat transfer was solved by finite
differences using an implicit scheme. The appropriate mesh size in the direction corresponding to the heat
flux resulting from the fire was defined. The temperature results of the two dimensional simulation does
not depend on the dimension of the mesh size in the horizontal direction (perpendicular to the heat flux).
