A Non-Singular Boundary Element Method for Interactions between Acoustical Field Sources and Structures
نویسندگان
چکیده
Localized point sources (monopoles) in an acoustical domain are implemented to a three dimensional non-singular Helmholtz boundary element method the frequency domain. It allows for straightforward use of higher order surface elements on boundaries problem. will been shown that effect monopole ends up right hand side resulting matrix system. Some carefully selected examples studied, such as near and within concentric spherical core-shell scatterer (with theoretical verification), curved focusing multi-scale multi-domain acoustic lens.

Non-Hyper-Singular Boundary Integral Equations for Acoustic Problems, Implemented by the Collocation-Based Boundary Element Method
The weak-form of Helmholtz differential equation, in conjunction with vector test-functions (which are gradients of the fundamental solutions to the Helmholtz differential equation in free space) is utilized as the basis in order to directly derive non-hyper-singular boundary integral equations for the velocity potential, as well as its gradients. Thereby, the presently proposed boundary integr...
متن کاملApplying Legendre Wavelet Method with Regularization for a Class of Singular Boundary Value Problems
In this paper Legendre wavelet bases have been used for finding approximate solutions to singular boundary value problems arising in physiology. When the number of basis functions are increased the algebraic system of equations would be ill-conditioned (because of the singularity), to overcome this for large $M$, we use some kind of Tikhonov regularization. Examples from applied sciences are pr...
