Software company Machine Works announces the availability of a new reference example for CAE defeaturing. Polygonica is a component software library for working with polygon meshes that helps companies in a range of industrial markets solve complex 2D and 3D geometrical problems.

Preparing models, particularly models in mesh form, for CAE simulation, can be a very time-consuming process. Often it can be the most time-consuming and labour-intensive part of the CAE process.

There are several challenges, which include

Creating a topologically correct, watertight mesh free from strictly defined mesh errors such as self-intersections and non-manifold geometry

Removing small mesh artefacts that can cause the CAE remesher and solver problems

Removing small features that lead to the CAE remesher creating unnecessarily dense meshes, leading to longer runtimes, without improving the accuracy or reliability of the overall result

Polygonica has range of tools that facilitate user-guided feature removal on ‘dumb’ polygon meshes i.e. where there is no known BREP structure or feature tree e.g. this is a cylinder, this is a cone, this is a Nurbs surface etc.

A typical workflow involves:

Augmented selection — use a range of tools to facilitate easier selection

Deletion of selected faces/triangles from the mesh

Advanced hole filling — use Polygonica’s advanced curvature sensitive hole filling to close the gaps created by the deletion of the selected faces

Optional remeshing — use Polygonica’s remesher to improve the quality of triangles in the selected region, or across the entire mesh
