| Feature | How It Helps | |---------|----------------| | | Models molten metal or hot fluid motion, including turbulence and free surfaces. | | Heat transfer & solidification | Tracks temperature gradients, latent heat release, and solid fraction evolution — critical for predicting hot crack susceptibility. | | Thermal stress coupling | Optional structural solver (or exported thermal loads) to compute thermally induced strains. | | Non-Newtonian viscosity | Captures rheology of semi-solid alloys, where hot cracks typically form. | | Porosity & feeding flow | Detects regions of poor liquid feeding that lead to shrinkage porosity — often linked to hot cracks. |
The solver must account for how fluid pressure initiates and propagates a crack aperture. Thermal Shock: flow 3d hydro crack hot
Modern workflows often use (Finite Discrete Element Method) to simulate how fractures initiate and propagate in 3D. This allows for: | Feature | How It Helps | |---------|----------------|
: Accurately simulating the creation and propagation of fractures in rock formations is highly complex and requires detailed knowledge of rock mechanics. | | Non-Newtonian viscosity | Captures rheology of
