Preparing the model for 3D Fill+Pack analysis

Compulsory modeling tasks must be performed or the analysis will not run. There are also some optional modeling tasks that can be performed if required.

Compulsory modeling tasks

In order to run a 3D analysis, you must have a 4-noded, tetrahedral-element meshed part model, either

• created in a CAD system and imported,

  or

• created on a surface model using tools avaiable in this product.

Analysis setup options

Select a pressure control point.

Modeling gates

When using 3D analysis technology and Fill+Pack analyses without a modeled gate or runner system, there is a critical significance of implied gate size on the predicted injection pressure.

Note: When running a Fill+Pack analysis using 3D analysis technology with beam elements, there must be more than one beam element between the injection node and the tetrahedral elements.

If no gate is modeled (direct injection) the gate size is automatically assigned based on the part geometry, or in the case of small parts the average facet size of the tetrahedral elements on the surface around the injection location. The gate diameter can also be manually specified from the Solver Parameters dialog.
