[Wien] error showing : libmkl_intel_lp64.so: cannot open shared object file

[shamik chakrabarti]

Dear Laurence Marks Sir and wien2k users,

                Sorry for late reply to this mail. Actually I was trying to
solve the compilation problem and eventually able to solve it by getting a
hints from the previous mail in the mailing list. After changing -pthread to
-lpthread in Linker flag OPTION we saw that wien2k was able to run as
before.

Sir, I now want to discuss the next problem about 130 iterations. I was
running calculation on a spinel compound with space group Fd3m and having
different occupancies at the same lattice site. To incorporate those
occupancies we have generated a 56 atom supercell with target lattice
primitive. By giving the lattice parameters and structural coordinates of
the supercell in another software viz. powdcell we have observed that it is
giving the same XRD pattern as we have obtained experimentally. *So as far
as the structural model is concerned it should be alright.* We have used 14
K points and mixing parameter 0.2 with mixing scheme MSR1.
 Now my questions are the following:

(i) As it is an oxide material having insulating property, we have used
GGA+U approach with a U = 5eV for Fe. Is it possible that
   different U value may improve the convergence?
(ii) Should we go for MBJ type potential?
(iii) Except the above two alternatives is there any other approach which
can help us to reach near the actual physical model by
     improving the convergence?

Any response will be very helpful for us. Thanking you,

with best regards,
