Thin shell
How does SnS works when a model is made solely of surfaces and not volumes (typically, a hull of a ship and its bulkheads where the thickness is not taken into account)?
Most of Naval studies are performed using shell elements. Is there that possibility in SnS? And how would volumetric details like details of sea-fastening, or masts or pedestals or more complicated mechanical artefacts would be handled in a global model (ie. both thin shells and solids)?
Thanks for the precisions and good luck with the development.

Hi Mael,
Good suggestion. At the moment S&S only supports a mono volume.
Being a naval architect I've done some testing at a structure and wrote down some experiences both in a S&S discussion and a blog article
As you can see, I had to use a mono volume and that involves a lot of proper solid modeling as well as long calculation times when a structure is more complex.
It depends on the fundamental S&S technology whether the S&S team can add a multi surface feature. Hope to hear from them about this.

If I take the question literally. then the short answer is "no", because we are not planning to introduce special kinds of elements, dimensional reduction and heterogeneity, heuristic interfaces, and so on. Such models are very complex to construct and to analyze, and this would undermine the philosophy behind Scan&Solve technology.
Having said this, there are other ways to handle geometric complexity, high aspect ratios, and multiple scales within the same model. In particular, Scan&Solve is well suited for multi-resolution and multi-scale methods -- that could be applied directly and automatically to full three-dimensional complex assemblies. This means that in the future, you can expect to see substantial improvements in efficiency and in the types/complexity of models handled by Scan&Solve, but without using the traditional means of special-purpose elements, complex interfaces, meshing, and simplification.
