The technique excels the conventional generalized curvilinear technique using contravariant velocity, covariant velocity and pressure as variables for three-step time marching, especially in that normal acoustic impedance boundary conditions which are indispensable in practical application are also presented. Validation of the technique through comparison against orthogonal FDTD with staircasing applied in irregularly-shaped sound field shows suppressions of phase error in initial time marching stage and diffusion from staircased boundaries.", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "46487", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Oshima, Takuya"}]}]}, "item_5_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "日本建築学会"}]}, "item_5_relation_31": {"attribute_name": "異版である", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://ci.nii.ac.jp/naid/110004788047", "subitem_relation_type_select": "URI"}}]}, "item_5_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "社団法人日本建築学会"}, {"subitem_rights": "本文データは学協会の許諾に基づきCiNiiから複製したものである"}]}, "item_5_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_5_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AA11830377", "subitem_source_identifier_type": "NCID"}]}, "item_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "13480685", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "大嶋, 拓也"}], "nameIdentifiers": [{"nameIdentifier": "46486", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-07-30"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "110004788047.pdf", "filesize": [{"value": "838.5 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 838500.0, "url": {"label": "110004788047.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/3974/files/110004788047.pdf"}, "version_id": "a2d6b247-26f6-4d38-b453-c762edbbf778"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "音場数値解析", "subitem_subject_scheme": "Other"}, {"subitem_subject": "FDTD法", "subitem_subject_scheme": "Other"}, {"subitem_subject": "一般曲線座標系", "subitem_subject_scheme": "Other"}, {"subitem_subject": "法線方向音響インビーダンス境界条件", "subitem_subject_scheme": "Other"}, {"subitem_subject": "階段近似", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "反変速度-圧力交互時間進行による一般曲線座標系FDTD音場解析手法", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "反変速度-圧力交互時間進行による一般曲線座標系FDTD音場解析手法"}, {"subitem_title": "反変速度-圧力交互時間進行による一般曲線座標系FDTD音場解析手法", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "425"], "permalink_uri": "http://hdl.handle.net/10191/18375", "pubdate": {"attribute_name": "公開日", "attribute_value": "2012-06-05"}, "publish_date": "2012-06-05", "publish_status": "0", "recid": "3974", "relation": {}, "relation_version_is_last": true, "title": ["反変速度-圧力交互時間進行による一般曲線座標系FDTD音場解析手法"], "weko_shared_id": null}
