FEMAP V11.3: Geometry CleanUp
The tool Feature Removal from the Meshing Toolbox in the new release of FEMAP V11.3 has new capabilities to help users to properly idealize geometry for FE meshing purposes:
• POINT: used to remove any selected points which are redundant..
[ul]
[li]NOTE: When attempting to remove multiple points, all of which were selected at the same time, the tool is designed to not remove certain points which are shared by curves with a large difference in curvature. There may be instances where the curvature is not really that different, for instance when a point is shared by two splines, but the tool will not remove that point due to this designed limitation. When only a single point is selected, the tool uses a more aggressive approach, which may allow the tool to remove these points, but only when selected one-by-one., OK?.[/li]
[/ul]
• CURVE: here we have the following options, Basic, Aggressive & Combine Surfaces.
[ul]
[li]BASIC (default): uses features of the Geometry > Solid Cleanup command to try to remove redundant curves.[/li]
[li]AGRESSIVE: uses functionality from the “Parasolid Bodyshop” to try and “compress” very small curves out of geometry by bringing the curve’s endpoints together, then “healing” the geometry to maintain valid geometry. It is quite possible to change the topology of the geometry when using this option.[/li]
[li]COMBINE SURFACES: uses the Parasolid kernel to calculate a new surface through the original two surfaces, which share the selected curve. If successful, all the curves sharing the original two surfaces are removed, as they become redundant. This option will also remove any redundant points on the ends of the removed curves.[/li]
[/ul]
Best regards,
Blas.
