This boundary condition also means that the magnetic field is zero in the normal direction to the boundary. That is, the magnetic field must be tangential to this boundary. As a consequence, this boundary condition has the physical interpretation of a boundary through which current can only flow...
No flow or Symmetry for boundary condition?Login
I'm thinking that these may be a finite element problem and i should try with a finite volume solver. Any thoghts are welcome and thanked Hello Felipe Suarez Your Discussion has gone 30 days without a reply. If you still need help with COMSOL and have an on-subscription license, please v...
Hi all, I am new to Comsol and am trying to model a simple 2D composite unit cell (concentric circle in a square) with periodic boundary conditions. As a guide I am using a paper by Drago et al. (dx.doi.org/10.1016/j.compscitech.2006.02.031). In this paper, the symmetry of the...
(COMSOL Multiphysics 5.4). The symmetry-broken SSP was sub-divided into very small but finite size meshes, and each mesh is governed by a set of characteristic equations which describe its physical properties and boundary conditions. Although there is no general closed form solution of the ...
The full-wave numerical simulations in the main text were performed using the Pressure Acoustic module coupled with Linearized Potential Flow module of the commercialized finite-element software COMSOL Multiphysics 5.4, assuming a mathematically imposed, time-independent bias velocity as the background flow...
These include Symmetry, Symmetry Plane, and Antisymmetry boundary conditions, among other types of symmetry boundary conditions (e.g., Sector Symmetry), which enable you to specify the symmetry planes or lines of symmetry in your model.The Symmetry boundary condition that is used in the Shell-...
It is, however, possible to set up such boundary conditions by editing Periodic Condition constraints in Equation View. --- Henrik Sönnerlind COMSOL Mirhan Özdemir Send Private Message Flag post as spam Posted: 4 weeks ago Dear Henrik Sönnerlind, Thank you very much for your respo...
(with or without gain/loss) and the variation of the eigenfrequencies of the PT-symmetric sensors are investigated with the FEM-based eigenfrequency analysis method using COMSOL Multiphysics. All the boundaries are set as scattering boundary conditions. The unidirectional light propagation feature of ...
while incidence from the right-hand side leads to a clockwise loop. We calculated the wave transmission in the system, and the desired initial state at the boundary was excited by a pre-calculation of the eigenmodes using the boundary mode analysis module of COMSOL42. The distributions of the...
