10:00 - 10:30
General outline for approaching simulations – 20-30 minutes
- What is important to consider when modeling casting processes
10:30 – 11:15
Setting up problems
- Tools for STL file visualization and repair: Minimagics, STL viewer and ADMESH
- Using the STL file library
- FAVORization
- Verifying setup by running pre-processor
- Pre-processor
- Setting up restart simulations
11:15 – 12:00
Meshing and model size: a balance between accuracy and speed
- Meshing, multi-block, nested blocks
- Unstructured memory allocation (UMA)
- Thermally active layer
- Constant, non-uniform mold temperature model
12:30 – 1:30 LUNCH
1:30 – 2:15
Physical models
- Filters
- Air entrainment and surface oxide defect tracking
- Micro- and macro-porosity models
- Solidification
- Heat transfer coefficients
- Exothermic sleeves
- Counter-rotating inlet flow for centrifugal casting
- Flow-rate boundary condition
- Using mass/momentum sources to model inlets
2:15 – 3:00
Numerical options
- Pressure solvers
- VOF options
- F-packer
- Implicit advection
- Solver Diagnostics:
- volume error
- pressure convergence problems
- convective flux problems
- Changing numerical options at runtime
BREAK ... 3:00 – 3:15
3:15 – 3:45
Using General Moving Object model
- Coupled-motion vs. prescribed
- Coupled-motion shot sleeve plunger model
- Motion limiters
- Examples
3:45 – 4:15
Output and post-processing
- Reducing flsgrf file size: use selected data output
- Special output
- Using STL files to display geometry
- Interpreting results
- Third-party postprocessing: Fieldview, Tecplot, Ensight
4:15 – 4:45
Reducing model size and CPU time
- Parallel execution
- CPU time diagnostics
- Hardware recommendations (including graphics cards)
