Web2) Also I understand that these boundary conditions just mean that like going to the next Riemann sheet, you should first go around a complete loop around the branch point. So at every point, if we make a complete loop and try to reach the same point, we go to the next Riemann sheet and that's the meaning of these boundary conditions. WebFurthermore, boundary conditions are strongly related to the validation and verification of the FE model so erroneous b.c can be realized during this process. Thank you again!
