Hello everyone
I’m here again to ask for help… last time you helped me and for this I thank you…
using the finite element method (FEM)… I need some tips..
-
I have to set omega which should be the seventh eigenvalue calculated with NDEIgensistem but I can not set it…
-
I should set the theta corner which is the angle of entry of the sea into the port and should have a value included by ??<?/2 measured in radians
I attach the notebook where I tried several attempts
Trusting in your help, I thank you
