Hey Guys i am looking forward to calculate a LBA for cylindrical shells with different boundary conditions (bc1r, bc1f, bc2r and bc2f). The eigenvalues/eigenforms that i get for small shells (Lenght<300mm), however, do not look right and do not really converge. The code is attached as well as a picture of one eigenform.

Thanks
