[Wien] First time doing volume optimization

Dear wien2k experts

     I am doing volume optimization of one peroskite structure and want to
calculate the optimized lattice parameter. It is a perfect cubic structure
and experimental lattice parameter is 4.0029 angstrom. After initilizing
all the step, I have clicked on optimize (v,c/a) and it wanted input
parameter for a:b:c ratio. For that I have given as -2, -2, -2 and run the
calculation. It has run with no error and came out successfully. According
to the manual, a file case.outputeos should have been created . But I have
not found. I have the following question:


(1) what should be the generally  appropriate value to put for the a:b:c
for the volume optimize?

(2)After run, where can I find my optimize lattice parameter value ?

(3) In the prepare input file for the k-point I have given 2744 number of
k-points. I wanted k-mesh as 14*14*14. But   in the created
"cubic_phase_vol__-2.0.scf" it is showing number of k-points is 84. Why?


I am giving the day file below so that some body can comment it is
correctly done or not?
My day file is following:
