By modifying the forcing term and the definition of the physical quantity, the LBM eliminates the error term depending on the relaxation time. The calculations for the Poisson equation with sinusoidal source show that the LBM obtains the second order convergence rate in space and that there is good agreement between the numerical and the analytical solutions. I investigate the computational efficiency by comparative study with the finite difference method (FDM) including the Jacobi, the Gauss-Seidel, and the SOR methods. The computational results for the Helmholtz equation make clear that the approximate relaxation time makes the LBM faster than the SOR method, or more accurate than the FDM. In addition, there is a trade-off between the efficiency and the accuracy provided by the adjustment of the relaxation time in the LBM.","subitem_description_type":"Abstract"}]},"item_2_description_40":{"attribute_name":"資源タイプ(DSpace)","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_2_description_6":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"計算数理工学論文集 9, 7-12.(2009)","subitem_description_type":"Other"}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"10469","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"9000003798740","nameIdentifierScheme":"CiNii ID","nameIdentifierURI":"http://ci.nii.ac.jp/nrid/9000003798740"},{"nameIdentifier":"50308699","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://nrid.nii.ac.jp/nrid/1000050308699"}],"names":[{"name":"Seta, Takeshi"}]}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本計算数理工学会"},{"subitem_publisher":"Japan Society for Computational Methods in Engineering"}]},"item_2_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"瀬田,  剛"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-02-09"}],"displaytype":"detail","filename":"KeisanSuri_9_007to012_Seta.pdf","filesize":[{"value":"542.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KeisanSuri_9_007to012_Seta","url":"https://toyama.repo.nii.ac.jp/record/15561/files/KeisanSuri_9_007to012_Seta.pdf"},"version_id":"a061b4b5-2d84-48d3-9c28-f0984010c874"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Lattice Boltzmann Method","subitem_subject_scheme":"Other"},{"subitem_subject":"Poisson Equation","subitem_subject_scheme":"Other"},{"subitem_subject":"Accuracy Analysis","subitem_subject_scheme":"Other"},{"subitem_subject":"Lattice Boltzmann Method","subitem_subject_scheme":"Other"},{"subitem_subject":"Poisson Equation","subitem_subject_scheme":"Other"},{"subitem_subject":"Accuracy Analysis","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":"ポアソン方程式に対する格子ボルツマン法の精度評価","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ポアソン方程式に対する格子ボルツマン法の精度評価"},{"subitem_title":"ACCURACY ANALYSIS OF LATTICE BOLTZMANN METHOD FOR THE POISSON EQUATION","subitem_title_language":"en"}]},"item_type_id":"2","owner":"19","path":["558"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-01-26"},"publish_date":"2018-01-26","publish_status":"0","recid":"15561","relation_version_is_last":true,"title":["ポアソン方程式に対する格子ボルツマン法の精度評価"],"weko_creator_id":"19","weko_shared_id":-1},"updated":"2023-07-25T14:32:56.669979+00:00"}
