Learn How to Save Computation Time with New Symmetry Feature

In Moldex3D R10, it is feasible to import a 1/2 or 1/4 model into Moldex3D Designer and use “Set configuration” for symmetry setting. Greatly enhanced in Moldex3D R11, the full model can be directly imported. Moldex3D Designer helps you find the best symmetry configuration step by step to save computation time with improved accuracy in a full 3D analysis.

The procedures to perform this setting are easy as follows:

1. Import a full model, including cavities and runners with symmetric configuration.


2. In Step2: “Build runner system”, click “Set symmetry configuration”. There are two symmetry setting options showing up: “Set configuration” and “Set removal”. Select “Set removal”.

3.  The sprue will be highlighted. Check the box of “Set this segment as symmetrical”. 

Now 3/4 model become transparent, signifying that only the other 1/4 model (not transparent) will be used as the model in the analysis. Click  to confirm this setting or choose “Next segment” for further symmetry setting if it is feasible.

      

4. After clicking “next segment”, another runner segment will be highlighted. Again, check the box of “Set this segment as symmetrical”. Now 7/8 model becomes transparent, signifying that only the other 1/8 model (not transparent) will be used as the model in the analysis. Click to confirm this setting. Because there is no more “Next segment” for further symmetry setting.

       

5. Go to Step 4: “Generate solid mesh”. Appropriate Symmetry boundary conditions are automatically applied to model after meshing.

       

6. Export solid mesh for analysis and view the simulation results accordingly. The analysis is done with 1/8 of the model without any additional modifications.
