Preparing a geometry for meshing

Discussion

Use the Modeling application to create or edit part geometry. Geometry creation in Simcenter 3D is parametric, with modeling operations stored as features in a history tree that is listed in the Part Navigator. This allows you to control and update the geometry efficiently throughout the modeling process.

You can create geometry manually using sketch-based modeling or import it from third-party CAD systems.

Sketch-based modeling

A sketch is a named set of 2D curves defined on a plane or path. Use Sketch to:

• Define profiles or typical cross-sections.
• Create detailed part features by sweeping, extruding, or revolving a sketch into a solid or a sheet body.
• Develop large-scale 2D layouts with hundreds, or even thousands, of sketch curves.

Modifying geometry before meshing

Before meshing, geometry often requires cleanup or simplification. For many models, you can use the Geometry Preparation and Synchronous Modeling commands. Sometimes, however, you need the tools available in the Modeling application.

Creating an associative copy of geometry

Before modifying an idealized part, you must first create an associative copy of the geometry you want to modify, using:

• Promote that copies selected solid or sheet bodies.
• WAVE Geometry Linker that creates associative links to bodies, faces, or edges.

Use WAVE Geometry Linker for greater control over what geometry is copied and when updates are applied.

Idealizing geometry

Geometry idealization simplifies the model prior to meshing and is performed on the idealized part. You can:

• Remove or suppress features.
• Split bodies to control mesh density.
• Create midsurfaces for thin-walled parts.
