Therefore, for calculating the band structures of V- and N-shaped seismic metamaterials, the periodic boundary conditions are applied on the lateral sides of the unit cells in Figure 1. Traction free and fixed ... WebWhen creating the periodic boundaries, I disable “Automatic Compute Offset” and input the offset manually, as the offset is the same for all angles of attack. However, when I close the interface setup window and re-open it, “Automatic Compute Offset” is enabled again…. Problem 2: This is causing issues in the parametric study.

WebJan 12, 2015 · The Floquet-Bloch theory provides a strategy to obtain a set of solutions of a linear ordinary equations system of the form where is the solution vector and the matrix is periodic such that for a certain period . At first sight it might seem that the solution of such a problem would have to be also -periodic.
WebAug 30, 2024 · A periodic boundary condition takes whatever boundary conditions is present (explicitly or implicitly) at the source boundary and projects it to the target boundary. Since this seems to be a source of confusion I have tried to further clarify this in the documentation. Here is what is documented now. WebFinally, we identify a number of complex waveguides for which dispersion curves can be found with relative ease by using the periodicity inherent to the Floquet boundary …
