Abstract: Methods, systems, and apparatus, including computer programs encoded on a storage medium, for distributed analysis of structures. One of the methods includes obtaining a geometric model of a physical structure; and performing an analysis of a structural characteristic of the physical structure, comprising: dividing, by a master node, the model into a plurality of subdomains using a plurality of separator surfaces, selecting, by the master node, a respective separator approximant for each of the plurality of separator surfaces, assigning each of the subdomains to a respective child node, providing, by the master node to each of the child nodes, information defining the subdomain assigned to the child node and information defining separator approximants for the separator surfaces bordering the subdomain assigned to the child node, and performing, by each child node, the analysis of the structural characteristic for the subdomain assigned to the child node using the information.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for modeling turbine parameters. One of the methods includes obtaining, along multiple points of a blade of a turbine from a minimum radius rmin of the blade to a maximum radius rmax of the blade, lift coefficients Cyi and drag coefficients Cxi. At the multiple points of the blade from rmin to rmax, corresponding components of an upstream fluid flow velocity vector uh,Ri and uφ,Ri and components of a downstream fluid flow velocity uh,Li and uφ,Li are obtained. Averaged directions βi of the upstream and downstream fluid flow velocity vectors are computed using the components of the upstream fluid flow velocity vector uh,Ri and uφ,Ri and the components of the downstream fluid flow velocity uh,Li and uφ,Li. The total torque M of the turbine is computed including summing, from rmin to rmax, (Cxi sin βi+Cyi cos βi).
