Numerical determination of eigenfrequencies and eigenmodes using the Method of Fundamental Solutions
نویسندگان
چکیده
In this work we show the application of the Method of Fundamental Solutions (MFS) in the determination of eigenfrequencies and eigenmodes associated to wave scattering problems. This meshless method has already been applied to simple geometry domains with Dirichlet boundary conditions (e.g. [8]). Here we show that a particular choice of point-sources can lead to very good results for a fairly general type of domains. Simulations with other types of boundary conditions are also considered.

The Method of Fundamental Solutions applied to the numerical calculation of eigenfrequencies and eigenmodes for 3D simply connected domains
In this work we consider the Method of Fundamental Solutions (MFS) applied to the calculation of eigenfrequencies and eigenmodes of 3D shapes. This meshless method was considered for 2D shapes (e.g. [1], [8]) and the application to 3D simply connected domains is analysed. We propose a choice of collocation and source points in 3D adapted from the algorithm presented in [1]. An example with Diri...
متن کاملReduced Formulae for Vibration of Continuous Beams with Application on Moving Loads
Abstract: The present paper concludes via an analytical method to reduced formulae for determining the eigenfrequencies and eigenmodes of multi-span continuous beams with spans of different lengths and bending rigidities in a very easy and efficient way. The rigorous determination of eigenfrequencies and eigenmodes allows us to focus on the derivation of the time function for the forced vibrati...
متن کاملEfficient Solution of Large-Scale Electromagnetic Eigenvalue Problems using the Implicitly Restarted Arnoldi Method
We are interested in determining the electromagnetic fields within closed perfectly conducting cavities that may contain dielectric or magnetic materials. The vector Helmholtz equation is the appropriate partial differential equation for this problem. It is well known that the electromagnetic fields in a cavity can be decomposed into distinct modes that oscillate in time at specific resonant fr...
متن کاملEigenmodes and eigenfrequencies of vibrating elliptic membranes: a Klein oscillation theorem and numerical calculations
We give a complete proof of the existence of eigenmodes for a vibrating elliptic membrane: for each pair (m, n) ∈ {0, 1, 2, . . .} there exists a unique even eigenmode with m ellipses and n hyperbola branches as nodal curves and, similarly, for each (m, n) ∈ {0, 1, 2, . . .} × {1, 2, . . .} there exists a unique odd eigenmode with m ellipses and n hyperbola branches as nodal curves. Our result ...
متن کاملShaken not stirred –On internal flow patterns in oscillating sessile drops
We use numerical (volume of fluid) simulations to study the flow in an oscillating sessile drop immersed in an ambient immiscible fluid. The drop is excited by a sinusoidal variation of the contact angle at variable frequency. We identify the eigenfrequencies and eigenmodes of the drops and analyze the internal flow fields by following the trajectories of tracer particles. The flow fields displ...
