Geometry-based Boundary Conditions

You can assign boundary conditions such as Injection Locations, Control Valves, and Mold Wall Temperatures directly on geometry entities.

In the PlasticsManager tree, expand Boundary Conditions (Geometry Based).

In addition to the mesh-based assignment of boundary conditions (applied to elemental nodes or elemental faces), you can assign boundary conditions directly on geometry. This enhancement lets you position Injection Locations or Control Valves more accurately, and associate the boundary condition assignments directly to geometry when changes to the part geometry occur.

The software saves the boundary conditions you create directly on a part's geometry in the .sldprt file. You need to share only the .sldprt file so that your team members can view the geometry-based boundary conditions on the model. Configuration-specific study features are also saved.

Geometry-based boundary conditions have limited support for shell meshes.

Injection Locations on Geometry

You can assign Injection Locations directly to a part's geometry before creating a mesh.

In the PlasticsManager tree, right-click Boundary Conditions (Geometry Based), and click Injection Location (Geometry Based).

Use sketch points or geometry faces that represent the gate cross-section (gate or injection area) to precisely position the Injection Locations.

Control Valves on Geometry

You can define Control Valve locations using geometry features before meshing.

In the PlasticsManager tree, right-click Boundary Conditions (Geometry Based), and click Control Valve (Geometry Based).

In the Control Valve (Geometry Based) PropertyManager, click one of the two options under Valve:

Manually select the control valve locations

Select the locations to add the Control Valves.

Automatically find intersecting surfaces

Select to automatically detect all potential Control Valve locations at the intersecting surfaces between cavity and runner bodies.

Mold Wall Temperature on Geometry

You can assign Mold Wall Temperature boundary condition directly to geometry faces before creating a mesh.

In the PlasticsManager tree, right-click Boundary Conditions (Geometry Based) and click Mold Wall Temperature (Geometry Based).

Pin the Mold Wall Temperature PropertyManager to create multiple Mold Wall Temperature definitions on several geometry faces.
