Thank you. I'm using the Oracle VirtualBox environment by default, so I guess it's not complied with PETSc complex arithmetic. By the way, is using complex coding approved or separate to real and imaginary parts? I read another discussion in gouglegroup said complex coding might lead to error for <u,v> <v,u> integral. But separate a problem into real and imaginary doubles the matirx size and DoFs, isn't it?
