In acoustic, linear potential flow frequency domain, measurement of band structures. As a beginner in COMSOL and unable to find relevant cases, the supplementary materials in the literature suggest(To calculate band structures, we set the Floquet periodic boundary conditions by setting ‘Pointwise Constraints’ to introduce the Bloch phase shift to the eigenfields. ) However, I am not yet familiar with the specific operations involved, such as setting expressions
