14.3. Interactions - Euler/Lagrange (3D)

This panel lets you set up interactions (coupling) between 3D Lagrange Parts and Euler Parts.

Coupling Type

Select the coupling type you want to use.

None

No coupling is defined.

Rigid

Fill Parts are used to define rigid boundaries for Euler.

Fully Coupled

Lagrange Parts interact with Euler Parts dynamically.

Weak Coupling

A fast method for having Lagrange and Euler Parts interact dynamically.

Cover fraction limit

The cover fraction limit. This is used to determine when a partially covered Euler cell is blended to a neighbor.

Euler subcycling

Select whether you want Euler subcycling On or Off

Euler-Lagrange/Shell interactions
Fully Auto

All structural parts will automatically be coupled with all Eulerian parts in the model. Shell parts will be thickened automatically to fit the initial Euler region they reside in.

Review

Displays your Euler-Lagrange/Shell interactions.

Semi Auto

You must manually select all structural parts that will be coupled with all Eulerian parts in the model. Shell parts will be thickened automatically to fit the initial Euler region they reside in.

Select

Selects the structural Parts you want to couple to Euler.

Review

Displays your Euler-Lagrange/Shell interactions.

Manual

You must manually select all structural parts that will be coupled with all Eulerian parts in the model and also define the artificial thickness of each shell part in the interaction.

Select

Selects the structural Parts you want to couple to Euler.

Thickness

Specifies the shell thickness you want to use for the coupling calculation.

Joins

Specifies which shells are to be joined for the coupling calculation.

Review

Displays your Euler-Lagrange/Shell interactions.

Weak coupling settings

Select the weak coupling settings.

Browse

Enables you to select the location and name of the weak coupling field files to be used.

Geometry for mapping

Selection of the Lagrange geometry that is used for the remapping. You can select the initial geometry or the current geometry.
