TL;DR: Stability and a priori error estimates in terms of the fine subdomain scale $$h$$h and the coarse mortar scale $$H$$H are established for fairly general grid configurations, assuming that the mortar space satisfies a certain inf-sup condition.
Abstract: We investigate mortar multiscale numerical methods for coupled Stokes and Darcy flows with the Beavers---Joseph---Saffman interface condition The domain is decomposed into a series of subdomains (coarse grid) of either Stokes or Darcy type The subdomains are discretized by appropriate Stokes or Darcy finite elements The solution is resolved locally (in each coarse element) on a fine scale, allowing for non-matching grids across subdomain interfaces Coarse scale mortar finite elements are introduced on the interfaces to approximate the normal stress and impose weakly continuity of the normal velocity Stability and a priori error estimates in terms of the fine subdomain scale $$h$$ h and the coarse mortar scale $$H$$ H are established for fairly general grid configurations, assuming that the mortar space satisfies a certain inf-sup condition Several examples of such spaces in two and three dimensions are given Numerical experiments are presented in confirmation of the theory

TL;DR: Wang et al. as discussed by the authors reviewed the development of traditional lime-based bond in ancient times and found that the application of organic materials in inorganic mortar was a sharp-cut characteristic during the developing process of construction gelled materials in ancient China.
Abstract: The development of traditional lime-based bond in ancient times was reviewed in this paper. It was proved by a lot of historical data that the application of organic materials in inorganic mortar was a sharp-cut characteristic during the developing process of construction gelled materials in ancient China. The important role sticky rice mortar ever played and the historical significance were revealed. Due to the excellent performance, such as high adhesive strength, good toughness, water-proof and so on, traditional mortar represented by sticky rice mortar should be one of the greatest technological contributions of the day in the world. Modern technology was employed in the study of the sticky rice lime mortar and the researching results of our laboratory and some researchers, including the composition and the mechanism of solidification, were also presented. It was found that the sticky rice acted as a matrix of bio-mineralization which affected the microstructure of the calcium carbonate crystal and there was cooperation between sticky rice and calcite produced during the solidifying of the sticky rice mortar, which maybe lead to the excellent performance of the mortar. Because of excellent performance and importance in science, sticky rice mortar can be regarded as one of the greatest inventions in construction history of China. Relative research of sticky mortar will be of importance for the exploring of ancient momentous invention and the repairing of ancient construction.
