Hello ,
I am expericencing one problem in the Elastic Wave module. Hereby, I try to reproduce the solutions in that article "S. Duczek, M. Joulaian, Numerical analysis of Lamb waves using the finite and spectral cell method Int. J. Numer. Meth. Engng 2013; 00:1–28" (One can find the problem in p.18-p.24). Here is the summary and the problem;
Pure A0 and S0 modes are excited by exciting the signals from 2 symmetric point source with opposite directions. COMSOL can grab resulted excitation structures but there are problems about wave velocities and grabbing small amplituted scattered waves. (Please see the images arrival of the wave to the integration point takes longer in COMSOL ). With the exact setup of problem COMSOL wave seems slower than the article. What could be the reason and how can be solved? Thank you in advance.
I already increase the mesh (max.size = 10 per wavelenght) and solve it again.
