The proposed model has low computational cost and achieves an accuracy of moderate fidelity for the aerodynamic loads for a given glider shape. In the geometry preprocessing steps of our model, lifting-wing surfaces are recognized, and wake panels are generated automatically along the trailing edges. The proposed aerodynamics model improves the potential theory-based panel method. Furthermore, a new quadratic expression for aerodynamic forces and moments is proposed. It consists of geometry-dependent aerodynamic coefficient matrices and has a continuous representation for the drag\/lift-force coefficients. Our model enables natural and real-time aerodynamics simulations combined with general rigid-body simulators for interactive animation. We also present a design system for original gliders. It uses an assembly-based modeling interface and achieves interactive feedback by leveraging the partwise precomputation enabled by our method. We illustrate that one can easily design various flyable gliders using our system.<\/jats:p>","DOI":"10.1145\/3185767","type":"journal-article","created":{"date-parts":[[2018,3,23]],"date-time":"2018-03-23T12:29:49Z","timestamp":1521808189000},"page":"1-12","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":10,"title":["Precomputed Panel Solver for Aerodynamics Simulation"],"prefix":"10.1145","volume":"37","author":[{"given":"Haoran","family":"Xie","sequence":"first","affiliation":[{"name":"University of Tokyo, Hongo, Bunkyo-ku, Tokyo, Japan,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takeo","family":"Igarashi","sequence":"additional","affiliation":[{"name":"University of Tokyo, Hongo, Bunkyo-ku, Tokyo, Japan,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazunori","family":"Miyata","sequence":"additional","affiliation":[{"name":"Japan Advanced Institute of Science and Technology, Asahidai, Nomi, Ishikawa, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2018,3,23]]},"reference":[{"key":"e_1_2_2_1_1","doi-asserted-by":"publisher","DOI":"10.1145\/1276377.1276502"},{"key":"e_1_2_2_2_1","doi-asserted-by":"publisher","DOI":"10.1109\/TVCG.2008.107"},{"key":"e_1_2_2_3_1","doi-asserted-by":"publisher","DOI":"10.1145\/1015706.1015733"},{"key":"e_1_2_2_4_1","doi-asserted-by":"publisher","DOI":"10.1145\/2010324.1964930"},{"key":"e_1_2_2_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.compfluid.2004.08.002"},{"key":"e_1_2_2_6_1","unstructured":"A.
