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.
