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.
