Number of Thickness
Layers (10-16) |
Shell |
Specifies the number
of
virtual layers used to discretize the equations
in the thickness direction. Default:
15
|
Mold/Melt coupled
iteration relaxation factor |
Shell/Solid |
The relaxation factor is a weighting factor that
mathematically regulates the effect of the iterative solution update
between the polymer and mold temperature fields. Default: 0.8
- Increasing this relaxation factor may
result in a faster convergence rate, but may introduce
numerical instabilities that can trigger convergence
problems.
- Reducing this relaxation factor may
contribute to a more stable computation, but at a
reduced convergence rate.
|
Maximum Number of
Mold/Melt iterations (8 ~ 15) |
Shell/Solid |
Limits the maximum number of iterations between the polymer and
mold analyses. If the solver does not converge to a steady-state
temperature within this limit, it assigns the temperature field
of the last iteration to be the steady-state result.
Default: 8
|
Mold/Melt iteration
relative tolerance (1.E-3 ~ 5.E-2) |
Shell/Solid |
Specifies the relative convergence tolerance of
the local mold temperature between the current and previous
iterative cycles. Default: 0.01
|
Mold temperature
iteration relaxation factor (0.2 - 0.8) |
Shell |
Active only for the Gauss iterative solver. Governs the iterative update of the mold
temperature field.
Reducing
this relaxation factor results in a more stable computation, but
at a reduced convergence rate.
Default:
0.4
|
Maximum Number of Mold
iterations (300 ~ 800) |
Shell |
Limits
the maximum number of internal iterations used by the algebraic
equation solvers (Preconditioned Conjugate Gradient (PCG) or
Gauss).
Default: 500
|
Mold iteration
residual error tolerance (1.E-8 ~ 1.E-5) |
Shell |
Convergence criterion for the iterative
algebraic equation solvers (PCG or Gauss). Iteration stops once the
norm of the residual errors over the whole solution domain is less
than the specified value. Reducing this
relaxation factor results in a more stable computation, but at a
reduced convergence rate.
Default:
1E-6
|
Tubular-element Gauss
integration points (4 or 6) |
Shell |
Specifies the number of Gauss integration points
contained in the line elements of the boundary element method
used for cooling channel or runner analysis. To prevent
instabilities, you can only use the values 4 or 6.
Increasing the number of Gauss points improves the solution
accuracy, but requires more computational time.
Default: 4
|
Triangle-element Gauss
integration points (4 or 6) |
Shell |
Specifies the number of Gauss integration points
contained in the triangle elements of the boundary element
method used for parts.
Default: 4
|
Solver
type |
Shell |
Specifies the type of algebraic equation matrix
solver. Default:
Preconditioned
Conjugate Gradient
(PCG) solver. Reaches convergence for most problems.
The
Gauss-Seidel iterative solver (Gauss) is an alternative solver, but
is less likely to obtain a converged result. |
Solver
type |
Solid |
Specifies the type of algebraic equation matrix
solver.
Default: Algebraic Multigrid solver (AMG).
The AMG solver reaches convergence for most
problems.
It
is faster and uses less storage than the
Preconditioned AMG solver (PCG-AMG). The PCG-AMG solver might
provide additional robustness,
but
at a significant storage and performance
cost.
|
Transient mold
temperature output interval (1~10) |
Solid |
Specifies the time step interval at which output for the mold
temperature data is available. The output data is the transient
temperature of the cavity wall for the Fill and Pack analysis.
Reducing this value saves more transient data, but increases
processing time. Default: 5
|
Local profile
resolution[X-Y Plot](1 ~ 3) |
Shell |
Specifies the resolution of the output data for
the history of temperature in each local area. A higher resolution
value saves more temporal data. Default:
1
|
Analysis
Method |
Solid |
Specifies the discretization method for the analysis.
- FVM: Finite volume method (cell-centered)
- FEM-Linear: Finite element method with
linear elements (node-based)
- FEM-Quadratic: Finite element method with
quadratic elements (node-based)
Default: FEM-Linear
