MMI_splitter_3D_FDFD issue

[YUJING-HE]

I have encountered a problem when running ~/emopt-master/examples/MMI_splitter_3D/mmi_1x2_splitter_3D_fdfd.py

[INFO] Building system matrices...
Traceback (most recent call last):

A[i, jEx] = 1jeps.get_value(xh+0.5divl,yh,zh-0.5*divl) # todo: partial grid steps

TypeError: Cannot cast array data from dtype('complex128') to dtype('float64') according to the rule 'safe'

It seems that the data types of Maxwell operator and its elements are not consistent.

I have already solve the problem by reconfiguring the installation of PETSc
PETSc configure option : --with-scalar-type=complex
