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
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-...
(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 FEM-based eigenfrequency analysis method (COMSOL Multiphysics) is utilized and the calculated results are shown in Fig. 2. Figure 2(a) manifests the large frequency splitting of the PCNC pairs when placed closely. When the gap is 100 nm, the frequency detuning is as high as 2.22...
Ivar KJELBERGCOMSOL Multiphysics(r) fan, retired, former "Senior Expert" at CSEM SA (CH) Posted:1 decade ago Hi A couple of comments on your model_disp: 1) understand you enforce a boundary condition bloxing X and increasing Y wih a parameter sweep ...
The near-field interference images were simulated by the finite element method using COMSOL Multiphysics. The electric field distribution of plain α-MoO3 shown in the inset of Fig. 2d was excited by a vertically polarized dipole source. In the simulations of PoCs, we considered a 3 × ...
If you can make a boundary at your mid stream line, then you can apply any equation on this boundary with some physics equation writing. Comsol always solves for "=0" so if you want to set a variable to a given constant you need to write (MyVariable - MyConstant) =0 plus any appro...
1- In 2D axisymmetric mode (r,z coordinates) I used in z, the axis around which I later I revolved the circle (cross-section of the coil loop) AXISYMMETRY as boundary condition, and the rest of the sides of the rectangle that represent the surroundings I used Magnetic Insulation as a...
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...
