hellow?
recently i'm trying to do a transinet anlysis in 2D plane strain of acoustic model according to block theory, a kind of periodic boundary condition is used with exp(i*k*r) . one point in the square domain is given an initial velocity or displacement?v=1 or u=1?? periodic boundary conditions is used on the boundary. if k is not equal to 0? one error occurs as failed to find consistent value, second_argument_must_be_real. i don't know how to handle this problem, hoping for your advice.
thank you!
