Symmetry Analysis

With the support of symmetry analysis, you can save simulation time by analyzing a part of a model instead of the full model. The model has to be symmetric about a plane or two planes of symmetry, or an axis (for circular symmetry).

To set a symmetrical runner:

  1. Create a Solid Mesh (Guide).
  2. Select Runner and Cooling System Design.
  3. In the Tetrahedral Mesh PropertyManager, select Set Symmetrical Runner.
Symmetry analysis is supported for these cases:
  • A single runner edge stream: one-half symmetry (T-Type), one-quarter symmetry (X-Type), circular symmetry
  • Multiple runner edge streams, where the second and third runner edge streams are changing directions with respect to the first runner edge stream: one-half symmetry (S-Type), one-half symmetry (T-Type), one-quarter symmetry (H-Type), one-quarter symmetry (X-Type)

Symmetry Types for Single Runner Edge Stream

Original cavity One-half symmetry (T-Type)
One-quarter symmetry (X-Type) Circular symmetry (five cavities)

Symmetry Types for Multiple Runner Edge Streams

Original cavity  
One-half symmetry (S-Type) One-half symmetry (T-Type)
One-quarter symmetry (H-Type) One-quarter symmetry (X-Type)
Circular symmetry (three cavities) Circular symmetry (three cavities with Mirror Runner selected)
Symmetry analysis is available for SOLIDWORKS Plastics Professional and SOLIDWORKS Plastics Premium.
