This manual is prepared to provide in-depth information for experienced Moldex3D users. In this manual, Moldex3D simulation results of log file, includes filling, packing, cooling, warpage will be interpreted.

If transient cooling is selected for analysis, the following line will be displayed in *.lgf.

The following message means program is transferring finite element mesh files for finite volume computing.

MFV stands for mesh file for finite volume

Where to open the log files?

The log files will be created after simulations are completed. It can be opened either via Analysis -> View Log (as the first figure below), or right click on Project Working Space -> View Log(as the second figure below).

*.lgf file contains information of mesh, material, process and solver options, etc. The detail and noticeable items will be illustrated as follows. <Mesh_Information> Mesh information includes the detail of product volume, geometry, and element numbers. If the solid analysis is performed, numbers of different solid element, tetra, pyramid, prism, hexa will be listed. If eDesign is performed, only the meshing level will be addressed, since the hexa element is used only. <Material_Information> Material information is detailed in *.lgf. Users can view the information not only via material wizard but also *.lgf. <Process_Condition_Information> All the process setting will be detailed in *.lgf for an experienced user to check the process conditions. Note that boundary condition addressed moldbase coefficients of heat transfers. <Fiber_Parameter> Note that if the selected material contains fiber, the fiber information will be listed in *.lgf <Fiber_Parameter> as follows.
<Solver_Options_Information> It is addressed the computation parameters set in Moldex3D Project. (1)This infers the time duration of each step. Range is 1~5. (2)If the analysis material contains fiber, fiber computation will be turned on by default. (3)If residual stress option of estimate in filling/packing stage was selected, Flow-induced Residual Stress Computation will be turned on. (4)Compressible flow is off by default. (5)There are three mesh types recognized in Moldex3D Project. For Solid models, Mesh Type= Solid mesh file. For eDesign models, Mesh Type= eDesign mesh file. (6)A criteria of accomplishment of filling calculation. Once the filling percentage reaches or over this number, filling analysis will be considered completed. (7)The cooling analysis type user selects. Two options are Transient Cool and Cycle-Average. (8)Program will turn the option of Stabilized Calculation on in default. (9)Number of computation process infers number of tasks of the project. This option can be set up at task manager within computation parameter wizard. (10)Moldex3D provides three options for moldbase HTC(Heat Transfer Coefficient), Automatically determined Heat Transfer Coefficient was selected, Set Heat Transfer Coefficient, Fixed Mold Temperature, referred by number 1, 2 and 3. (11)Number of inlets The process of filling is detailed in the format as shown below. Time (sec) is addressed the filling time and CPU (sec) is addressed the computation time for the current No. step. The following message means the filling process is switched from flow rate control mode to pressure control mode. >>> Switching over from filling to packing phase (1) CPU computation time excludes data transfer time. Note that Host and Client represent computation nodes such as myid0, myid1... |

The process of packing is detailed in the format as shown below. Time (sec) is addressed the packing time and CPU(sec) is addressed the computation time for the current No. step. <Summary> Comparing Weight information in *.lgf and *.lgp, the *.lgp includes the total injected material weight which is the summation of packing and filling stages. Also Clamping Force at EOF represents the maximum tonnage during the molding process. Volume filled from Gate shows the melt volume filled through each gate, which also represents gate contributions. |

For standard cool, the format of cooling calculation history is shown as the figure below. Time (sec) is addressed the Cooling time and CPU (sec) is addressed the computation time for the current No. step. Also, if standard cool is performed, the Solid cool analysis computation parameter will be listed. *.lgc of Fast Cool and Solid Cool are similar. However, there are some difference in *.lgc of Cycle Average and Transient analysis. Please see the following for detail illustration. •Cycle Average (1)Iteration Number. In this case, it is iteration number 1. While the complete (%) reaches 100. IterNo1 will be ended. When the temperature difference between cavity and moldbase is less than the required tolerance, cycle average computation will be ended and it completes cooling analysis. (2)Step number, *.lgc outputs analysis data every 3 steps. (3)Maximum and minimal cavity temperature. In this case, 220 is the melt temperature and 50 is the mold temperature. (4)Maximum and minimal mold temperature. (5)Percentage of Cavity / moldbase temperature computation in each iteration. (6)Computation consumed time for each step.
•Transient Cool (1)Cycle Number. In this case, it is cycle number2. When the temperature difference between two near cycles is less than the required tolerance, transient cool computation will be ended and complete cooling analysis. (2)Step number of cycle number2. *.lgc outputs analysis data every step. (3)Cooling time of each step. (4)Maximum and minimal mold temperature. (5)Maximum and minimal mold temperature. (6)Computation consumed time for each cycle.
•Cycle Summary (1)Maximum and minimum cavity temperature in the end of cooling analysis (2)Maximum and minimum mold temperature in the end of cooling analysis (3)Total heat dispersed by part (4)Total heat dispersed by background (air) (5)Total heat dispersed by channels (6)Once the variation is less than the required tolerance, cooling analysis will be ended and completed. (7)Tolerance of temperature difference |

The WARP license is necessary for warp analysis. Before starting the warp analysis, program will confirm if there is valid license. Mesh Quality Check displays the poor quality element number for warp analysis. Run setting information is relative with computation parameter setting. However, if user have unreasonable computation parameter setting, *.lgw will be corrected. (1) and (2) If residual number is less than convergence tolerance, the computation will be considered as completed. If the iteration number is more than Max. no. of iteration (50000 here), computation will also be ended due to diverging. |
