Flow 3d Hydro Crack Hot -

  • Run solidification/thermal evolution

  • Extract thermal gradients & strain rates

  • Identify crack-sensitive zones


  • For actual hot cracking simulation with melting/solidification, use FLOW-3D CAST or WELD module. This HYDRO-based method gives a first-order risk assessment for thermally-stressed components in water environments.

    Let’s apply flow 3d hydro crack hot to a real-world scenario: A concrete spillway chute develops transverse cracks after a sudden gate opening releases deep, warm reservoir water following a cold night.

    Step 1: Geometry Setup The engineer imports the chute geometry (length: 50m, slope: 2%). An initial "defect" (a 2mm deep score) is placed at the mid-point. Run solidification/thermal evolution

    Step 2: Thermal Initialization

    Step 3: The Simulation

    Result: The simulation predicts a "runaway crack" (full-depth fracture) within 10 seconds—a failure mode impossible to see with rigid-body assumptions.
