Turn off "Mutual Heating" or "External Heat Sources" temporarily.
When a cable carries more current than the surrounding soil can dissipate as heat, a situation can occur. The "hot crack" is the physical manifestation of this stress, often leading to:
Using unofficial versions or "hot cracks" of engineering software poses several dangers:
Given the 890°C solidus, “Cymcap hot crack” is a misnomer if referring to reflow (260°C). More likely, the cracks form during when Cymcap is applied as a slurry and fired at 900–1000°C (thick-film process). During that high-temperature firing, the alloy partially melts, and solidification shrinkage creates hot cracks. Later, reflow soldering exposes and propagates these pre-existing cracks.
