Examples of Application (ex.7)Thawing a beefburger in a household oven; QW-3D with QW-BHM Left: system view Right: dissipated power patterns through beef and bread, produced by QW-3D under the assumption of constant media parameters at either -20 deg or +20 deg. Left: temperature-dependent media characteristics automatically considered by QW-BHM option Right: resulting temperature pattern produced by QW-3D with QW-BHM. Due to thermal runaway effect, after 35 sec. of heating a hot spot is created in bread while beef remains frozen.
