Examples of Application (ex. 7) Thawing a beefburger in a household oven; QW-3 D with QW-BHM Left: system view Right: dissipated power patterns through beef and bread, produced by QW 3 D 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-3 D with QW-BHM. Due to thermal runaway effect, after 35 sec. of heating a hot spot is created in bread while beef remains frozen.
