Solver parameters allow you to configure the advanced settings in an analysis.
Topics in this section
Editing solver parameters
During an analysis, solvers calculate simultaneous equations based upon the solver settings. Within the Process Settings Wizard, you can alter the numerical parameter defaults and solver tolerances for the selected molding process.
Mesh/Boundary and Mesh tabs
For an accurate simulation, it is important that a minimum number of layers is defined through the thickness. The higher the number of laminae, the more accurate the result.
Intermediate Output tab
Intermediate output refers to how often the simulation results are updated during the analysis.
Convergence tab
Calculating results is an iterative process, performed at sequential time steps. With each iteration the results converge to a more accurate answer. The more iterations you perform, the more accurate the result, but the longer it takes to get a result.
Parallelization tab
Parallel solution technology is implemented as an option in the solver parameters to improve solution speed for Midplane and Dual Domain flow analyses using thermoplastic materials.
Restart tab
Restart files provide a snapshot of the simulation during an analysis and are used to safeguard against system failure, to pause long analyses, and to extend analyses.
Interface tab
The Interface tab provides a means to interface with 3rd party programs, such as Abaqus, ANSYS, NASTRAN and LS-DYNA.
Cool Analysis tab
The Cool Analysis tab of the Solver Parameters dialog is available to optimize cool analysis calculations according to your requirements.
Cool (FEM) Analysis tab
The Cool (FEM) Analysis tab of the Thermoplastics injection molding solver parameters (3D) dialog is only available for models with 3D mesh types.
Warp Analysis tab
The Warp tab is used to define the type of warp analysis, the stress results to output and what to consider in the calculation.
Stress Analysis tab
The Stress Analysis tab is used to specify the type of stress analysis, the parameters to include in the calculation and the matrix solver to use.
Fiber Analysis tab
Fiber filled materials can display anisotropic behaviour. The direction of the fiber in the final part can affect the mechanical properties of the part in that direction.
Miscellaneous tab
The Miscellaneous tab of the Solver Parameters dialog is used to set fiber orientation analysis settings.
Microcellular Analysis tab
The incorporation of a gas into the melt gives the final polymer an aerated structure. The bubble growth within the polymer needs to be defined.
Core Shift tab
Under the pressure of the injection process, the core half of the mold can be deflected. This will result in thickness variation of the part, and is a frequent problem with long, slender product such as vials, test tubes and pen barrels..
Fill+Pack and Flow analysis tabs
The Fill+Pack Analysis and Flow Analysis tabs are used to specify the solver settings you would like to use during a Fill+Pack analysis, using a 3D mesh type.
Microchip Options tab
The Microchip Encapsulation analysis simulates the encapsulation of semiconductor chips with reactive resins, which provides protection from hostile environments, facilitates heat dissipation, and enables electrical interconnection of the chips.
Thermoset Options tab
The Thermoset Options tab of the Reactive molding solver parameters (3D) dialog is used to specify a lower bound for the temperature value, when calculating the viscosity of the material.
Venting Analysis tab
Venting analysis is used to predict the effects of air pressure on the flow of polymer to aid in selecting suitable locations where vents may be placed in the mold to allow trapped air to escape the cavity.
