[Wien] FW: Error in lapw_mini

[Ghosh SUDDHASATTWA]

Dear Stefaan, 
Thanks for the mail. I have read the UG and also gone through the TiO2
example. I have also solved a few other cases on orthorhombic lattice before
I switched over to monoclinic case. 
I initially used the PORT option and I got the message of inconsistent
forces 
My command line was min -j 'run_lapw -I -fc 1 -i 40' 

Probably I should continue to use the PORT option with min -j 'run_lapw -I
-fc 1 -i 60' 
Or as Xavier says, I should reduce the RMT's.

What you write above shows that you do not know what a geometry 
optimization means. Did you ever go through the TiO2 example in the UG?

There are thousands of wien users. All of them are confronted with 
similar problems as you describe when they start learning. Most of them 
switch on their brain (quoting Gerhard Fecher) to solve it, and they 
succeed. (The proof: if they wouldn't, the volume of this mailing list 
would by 10-50 times larger.) Why don't you do it the same way?
