Add the Layered Shell–Structure Cladding multiphysics node () to create claddings between boundaries modeled using the Layered Shell and domains or boundaries modeled using the Solid Mechanics, Membrane, or Shell interfaces.

The Layered Shell–Structure Cladding node is only available with some COMSOL products (see https://www.comsol.com/products/specifications/)

Select the Layered Shell interface to couple.

Select the Structure — Solid Mechanics, Shell, or Membrane.

Select the Connection type — Shared boundaries or Parallel boundaries.

There is an automatic search for possible adjacent geometrical objects. If you want to modify the selections, select the Manual control of selections checkbox. Select the boundaries where the cladding is applied in the Boundary Selection section. If you clear it, the selections will be replaced by the automatic ones.

Select the Layered shell boundary — Top or Bottom to apply the cladding.

The connected area is slightly extended by a distance Δ. Select how to determine this Connection tolerance — Automatic or User defined. For Automatic, the tolerance Δ is set to 0.5% of the shell thickness, which allows for small inaccuracies on for example a curved geometry. By selecting User defined, you can modify the value of Δ.

Select the connected solid boundaries in the Boundary Selection, Layered Shell section and the corresponding structural boundaries in the Boundary Selection, Structure section.

Select the Layered shell boundary — Top or Bottom to apply the cladding.

In case of a shell structure, select the Shell boundary — Top or Bottom to apply the cladding.

The connected area is slightly extended by a distance Δ. Select how to determine this Connection tolerance — Automatic or User defined. For Automatic, the tolerance Δ is set to 0.5% of the shell thickness, which allows for small inaccuracies on, for example, a curved geometry. By selecting User defined, you can modify the value of Δ.

Select where to place the Constraints on — Layered shell boundaries or Structure boundaries.

When Parallel Boundaries is selected from the Connection type list, the Search method option shows available mesh search methods for the mapping operator between the source and destination boundaries.

The Closest point method is the default and most robust search method for the mapping operator.

The Manual method is an alternative search method which is computationally efficient but its robustness is determined by the Search distance and the Extrapolation tolerance.
