(often called "soil drying out" or "thermal runaway"), which can cause the soil surrounding a buried cable to crack and lose its ability to dissipate heat. A highly relevant blog post for this topic is
Step 4: Adjust Execution Parameters
Ensure cables are not overlapping. Overlapping geometries cause a mathematical singularity that the solver cannot process. Open Execution Options . cymcap hot crack

"Hot cracks" in underground cable trenches occur when high surface temperatures dry out backfill, creating a physical gap that acts as an insulator and causes catastrophic temperature spikes. CYMCAP software mitigates this risk by modeling thermal environments, enabling two-zone soil analysis, and calculating ampacity for specific backfill materials [1]. Preventing these failures requires using engineered backfill, setting conservative interface temperature limits, and utilizing real-time monitoring [1].

What is Cymcap Hot Crack?
2. Failure at Joints (Exothermic Welds):
This is the most common site for hot cracking. Exothermic welds (e.g., CADWELD) create a cast structure. If the fault current raises the temperature of the joint close to its melting point, the intergranular liquid films within the cast structure can separate under thermal stress. This results in a "hot crack" that severs the electrical connection exactly when it is needed most.
In cracked regions, EDS identified Mn-rich intermetallic phases (CuMn₃Ni) and trace P segregation at grain boundaries. These low-melting-point constituents solidify last and serve as crack propagation paths under tension.
