For the construction of public buildings, water supply and drainage construction is of great significance. Paying attention to water supply and drainage construction and rational use of water supply and drainage construction technology have an important positive impact on the completion of water supply and drainage construction of public buildings with quality and quantity. This paper focuses on the technical key of water supply and drainage construction in public building construction, hoping to bring some help to our public building construction.展开更多

In the eddy current region, the eddy current density J is solved by the finite element method (FEM) which is discretized by brick finite element mesh, while in the eddy current free re-gion, the magnetic field intensity H is solved by the boundary element method (BEM) which is dis-cretized by rectangular boundary element mesh. Under the boundary conditions, an algebraic equation group is obtained that only includes J by eliminating H. This method has many advan-tages over traditional ones, such as fewer variables, more convenient coupling between the FEM and the BEM and wider application to multiply-connected regions. The calculated values of two models are in good agreement with experimental results. This shows the validity of our method.展开更多
