The simulation of (also known as solidification cracking) using FLOW-3D —specifically through the FLOW-3D CAST and FLOW-3D HYDRO engines—involves complex Thermo-Hydro-Mechanical (THM) coupling. This process is critical in manufacturing (casting/welding) and geosciences (hot dry rock fracturing). 1. Mechanisms of Hot Cracking in FLOW-3D
To accurately simulate these cracks, FLOW-3D uses coupled solvers that integrate three primary domains: flow 3d hydro crack hot
to simulate the interaction between fluid injection and thermal stress. Mechanical Interactions : Account for stress shadowing The simulation of (also known as solidification cracking)
: Uses the Scheil-Gulliver solidification curve to identify when material is most vulnerable—typically when only a tiny fraction of interdendritic liquid remains to backfill voids. Mechanisms of Hot Cracking in FLOW-3D To accurately
Employs a Finite Element (FE) approach within the CFD framework to calculate deformations and stresses. 3. Applications in Industry Application Role of FLOW-3D Key Defect Monitored Metal Casting
While "hot cracking" (hot tearing) is a well-known defect analysis feature in FLOW-3D CAST
