Applicability of the proposed method is confirmed in comparison with diagonal preconditioned CG method (DIAG method) for two turbulence models, which are standard Smagorinsky model (SSM) and dynamic Smagorinsky model (DSM), and for two mesh resolution cases of Ny40 and Ny80 where the numbers of division in the spanwise direction of the analytical domain are 40 and 80, respectively. As a result, it is confirmed that convergence rate for pressure Poisson equation is improved and computational time is reduced for both SSM and DSM. The effect of speed up is larger for the Ny80 than Ny40 and maximum speed up is 137.6%.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Architectural Institute of Japan", "subitem_publisher_language": "en"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.3130/aijs.82.1621"}}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1881-8153", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "山下拓三", "creatorNameLang": "ja"}, {"creatorName": "Takuzo Yamashita", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "宮村倫司", "creatorNameLang": "ja"}, {"creatorName": "Tomoshi Miyamura", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "小河利行", "creatorNameLang": "ja"}, {"creatorName": "Toshiyuki Ogawa", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "熊谷知彦", "creatorNameLang": "ja"}, {"creatorName": "Tomohiko Kumagai", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_title": "複数の二次元コースメッシュを用いたマルチグリッド法による円筒屋根周りの三次元LESの高速化", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "複数の二次元コースメッシュを用いたマルチグリッド法による円筒屋根周りの三次元LESの高速化", "subitem_title_language": "ja"}, {"subitem_title": "Acceleration of three-dimensional large eddy simulation around cylindrical roofs using multigrid method with plural two-dimensional coarse meshes", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/5698", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-30"}, "publish_date": "2023-03-30", "publish_status": "0", "recid": "5698", "relation": {}, "relation_version_is_last": true, "title": ["複数の二次元コースメッシュを用いたマルチグリッド法による円筒屋根周りの三次元LESの高速化"], "weko_shared_id": -1}
