⚠️ If HYDRO lacks built-in thermal stress, use the Elastic/Plastic Stress option under Advanced Physics. flow 3d hydro crack hot
The crack hot keyword also applies to fatigue. Many dams crack not from a single thermal shock, but from thousands of mild cycles. | Model | Purpose | |-------|---------| | Heat
Flow-3D Hydro allows users to script transient boundary conditions (e.g., 8-hour hot sun, 16-hour cold night over a 10-year operational life). By coupling the General Moving Object (GMO) model with thermal stress, the software tracks cumulative damage. ⚠️ If HYDRO lacks built-in thermal stress, use
Key finding from recent user group meetings: Engineers using flow 3d hydro crack hot discovered that seasonal temperature swings cause "breathing cracks" (cracks that open in winter, close in summer). During the "open" phase, sediment-laden water enters. When the crack closes, the sediment grinds the concrete faces, preventing full healing and lowering the fatigue limit by 40%.
While "hot" usually implies thermal expansion, it can also mean near-boiling scenarios (e.g., cooling systems or fire events). The software tracks enthalpy (heat content). If water flashes to steam inside a crack, the volume expansion (1600x) acts like a hydraulic explosive, instantly propagating the crack.
