Anycasting帮助教程Viewing Results

Viewing Results anyPOST shows Final Results, Progress Results, Sensor, etc.. In Final Result Types, It is possible to confirm the changes of properties at each mesh point during the entire simulation process. On the other hand, it is possible to confirm temperature, pressure, and velocity at the storage time designated in Progress Result Types. Final Result Types Progress Result Types Final Result types In Final Result Types, you can check the changes of properties at each mesh point during the entire simulation process Final Result Types History Data Filling Time Filling Sequence Solidification Time Solidification Sequence Simple Shrinkage Analysis Temperature Gradient Reciprocal Interface Moving Velocity Files that are saved upon end of simulation. The details are as follows: Filling time Filling time Solidification time Solidification time Size of temperature gradient at critical solid fraction Moving velocity of iso-solid fraction which is based on critical solid fraction Average cooling rate until critical solid fraction is reached Local solidification time from start to end of solidification Value resulting from dividing the volume of the retained melt by the surface area when solidification of each mesh has reached critical value Volume of retained melt Cooling Rate Local Solidification Time Retained Melt Modulus Retained Melt Volume Advanced Casting Analysis Retained Melt Surfaced Area Surface area of retained melt Combined Defect Parameter Probabilistic Defect Parameter Microstructure Prediction Solute Diffusion Length Solute diffusion length Thermal Diffusion Length Thermal diffusion length Capillary Length Capillary length Combined Microstructure Combined microstructure length scale일 Length Scale SDAS Secondary Dendrite Arm Spacing due to coarsening model Nuclei Density Nuclei density calculated according to the MT-SK model Grain Size Grain size obtained from nuclei density (diameter) Mechanical Properties Vickers Hardness Tensile Strength Elongation History Data In the history data, the time of filling or solidification is recorded. Using this data, you can observe the filling and solidification patterns and make as the movie file by animation. Filling Time Possible to continuously view filling time Possible to continuously view empty zone during filling when Inverse Contour is used Solidification Time Filling Sequence Possible to continuously view solidification time Possible to continuously view retained melt during solidification using Inverse Contour Has the same physical meaning as filling time, but displays filling sequence according to time in more detail. Especially, more useful when the free surface waves Has the same physical meaning as solidification time, but displays solidification sequence according to time in more detail. Especially, possible to examine in detail the re-melting zone Solidification Sequence Simple Shrinkage Analysis Shrinkage defects are occurred due to melt shrinking during the solidification process. In order to obtain a sound casting, shrinkage defect must be controlled. To predict these defects, the following data is used 1. The basic data - the solidification time of history data, temperature gradient, cooling rate, local solidification time, etc. 2. The advanced data - retained melt volume, retained melt surface area and retained melt modulus These have been developed by AnyCasting. The analysis is categorized as follows depending on prediction target. Prediction of Microporosity Temperature Gradient Reciprocal Interface Moving Velocity Cooling Rate Local Solidification Time Size of temperature gradient at critical solid fraction Moving velocity of iso-solid fraction based on critical solid fraction Average cooling rate until critical solid fraction is reached Local solidification time from start to end of solidification Prediction of Microporosity Resulting from Isolated melt and False Shrinkage cavity in Spheroidal Graphite Nodule Retained Melt Modulus Value resulting from dividing the volume of the retained melt by the surface area when solidification of each mesh has reached critical value Volume of retained melt Surface area of retained melt Retained Melt Volume Retained Melt Surfaced Area Note Critical solid fraction of the parametric model acts as the criterion for microporosity. Critical solid fraction of the gravity shrinkage model is the criterion for macroporosity and false shrinkage cavity. Advanced Casting Analysis This analysis method is used to combine two basic parameters or statistically calculate the probability that shrinkage will occur from basic or combined parameters. There are two functions. Combined Defect Parameter Probabilistic Defect Parameter Combined Defect Parameter Set the combined defect parameter. This is made by a combination of two basic parameters. User Interface Click on Combined Defect Parameter in Final Result->Advanced Casting Analysis and the following window will load.

It is possible to edit existing combinations. The setting dialogue is same as those of the Add function. If you select the Niyama model and Feeding Efficiency model, the dialogues are as follows.

Note The causes of shrinkage are very diverse, thus the prediction parameters must also be applied differently according to the case. It is important to find parameters or combination of parameters that are most suitable on the case. This software provides various basic parameters and enables users to freely combine parameters. Probabilistic Defect Parameter This model statistically calculates the probability from the basic or combined parameter. Using this, it is easy to observe risk zone of shrinkage generation. User Interface Select Probabilistic Defect Parameter in Final Result->Advanced Casting Analysis and the following window will load. Defect Parameter Defect Potential Critical Volume Fraction Parameter to be used in calculating defect probability Possible to select all basic parameters and combined parameters Volume fraction of defects The criterion to display the value of parameter of each mesh on screen Should the volume fraction exceed the critical value, the probabilistic parameter value is displayed graphically on screen The default value is set to 0.5 and may be changed within 0 and 1. There is a direct proportion between the value of selected parameters and defect probability There is an inverse proportion between the value of selected parameters and defect probability Reading the saved result file(*.prd) calculated previously. Direct Proportion Inverse Proportion Open Saved Result Save Probabilistic Defect Parameter Results As it takes much time to obtain probabilistic defect parameter, it is better to save results to check it in the next time. 1. Set as above and click on 'OK'. anyPOST performs the calculation and shows the results on screen. 2. Select Parameters -> Save Probabilistic Defect Parameter in the menu and the save window will load. 3. Designate the file name and click on Save. Note When defect prediction parameters is distributed widely, it is difficult to observe the danger zone where defects may occur. In such a case, use this parameter statistically calculated by defect prediction parameters and then it is possible to observe the zone easily. Microstructure Prediction Microstructure is predicted by the special model such as specific lengths, Secondary Dendrite Arm Spacing (SDAS) and the MT-SK model. SDAS is obtained by coarsening model and MT-SK model is based on nuclei generation and growth velocity. The microstructure prediction parameters listed below are the combinations of special lengths and these models. Solute Diffusion Length Thermal Diffusion Length Capillary Length Combined Microstructure Length Scale SDAS Nuclei Density Grain Size Solute diffusion length Thermal diffusion length Capillary length Combined microstructure length scale Secondary Dendrite Arm Spacing due to coarsening model Nuclei density calculated according to the MT-SK model Grain size obtained from nuclei density (diameter) Combined Microstructure Length Scale Set the combined microstructure length scale.
