Continuing work on mesh enhancement has focused on optimizing the surface mesh for Dual Domain and 3D technologies.
In the past, a surface mesh around small features contained many small, high aspect ratio triangles.
This release introduces a more even surface mesh with a gradation of mesh size from the feature to the surrounding mesh.
As a Dual Domain surface mesh is the basis of a 3D mesh, this improvement also flows through to 3D meshes.
This same technology has also been applied to the following situations.
- Mold surfaces
- The points of contact between the mold surface and cooling lines or feed systems also have the local mesh refinements.
- Gate and beam-cavity connections
- Where the plastic enters a mold is a dynamic region for plastic flow analysis. A more uniform and refined mesh helps capture information from this area.
Compared to the 2014 release:
- For all models tested, the Maximum and average aspect ratio reduced significantly.
- STL models had an improved Match ratio. CAD models had similar Match ratios.
- Element count increased for STL models while CAD models had a similar count.
