Crystallization dialog
This dialog is used to set crystallisation simulation parameters.
These properties are required when the option to perform a crystallization analysis is selected.
| Dialog component | Explanation |
|---|---|
| Quiescent nuclei number coefficients | These values are measured constants in the equation that defines the number of activated nuclei in the quiescent condition. |
| Equilibrium melting temperature (Teql) | This is the measured equilibrium melting temperature under zero pressure. |
| Growth rate (Hoffman-Lauritzen) coefficients | These values are measured constants in the equation that defines the temperature-dependent growth rate of crystals. |
| Glass transition temperature (Tg) | This value is the measured temperature at which the melt-to-solid transition occurs. |
| Relaxation time at reference temperature (T_rlx) | This value is the time required for the material to relax after elongation, measured at a specified temperature. |
| Free energy coefficients | These values are parameters in the equation that defines the nucleation rate during flow. |
| Index (q_indx) for free energy | This value is a measured parameter that defines the enhanced nucleation due to shearing flow. |
| Non-linear spring parameter (bFENE) for FENEP | This value is a constant in the equation that defines the change in free energy due to shearing flow. |
| Parameter for Shish (gL) | This value is a constant that defines the shape of the crystals resulting from shearing flow. |
| Parameter for shrinkage anisotropy (GL2) | This value is a constant that defines the enhancement effect on flow-induced shrinkage anisotropy. |
| Viscosity modifying coefficients | These values are measured parameters that define the increase of viscosity due to the growth of crystals. |
| Crystallization effect on specific heat (Cpcef) | This value is a constant that defines the effect of crystallinity on the material's specific heat value. |
| Fiber effect on crystallization (cN) | This value is a constant that defines the enhancement effect of the presence of fiber fillers on crystallization. |
| Ultimate crystallinity (X_Inf) | This value is the maximum value of relative crystallinity (defined as the ratio of the crystalline volume at a given time to the total volume) that can be achieved for the material. |
