A Fully Auto option has been added when using the Fully Coupled Euler-Lagrange coupling method. This option will fully automate the set up of the Euler-Lagrange/Shell coupling. All structural Parts will be coupled to the Eulerian Parts in the model, and all shell Parts in the model will be thickened in such a way that they will fit the region of the Euler mesh they initially reside in.

There is also a Semi-Auto option where only the set-up of the shell coupling is automatic. The coupling properties of any other structural parts remain unchanged.

Significant improvements to the robustness of shell coupling at T-sections (or locations where more than 2 shell faces are connected along a common edge) have been made. Only the normal of relevant shell elements is used to obtain a smooth coupling surface at those locations, which is a similar procedure as is available in the existing Joins options for the Manual coupling setup of structured parts.

Improvements have been implemented for the treatment of cover fractions for fully-constrained rigid parts. These cover fractions are now only calculated at the start of the analysis. Furthermore, such parts can be included in models also containing other moving rigid and/or flexible parts. Therefore, when using Full Coupling, fully-constrained rigid parts (and structured Fill parts) are more efficiently calculated in combination with other moving rigid and/or flexible parts.
