Dear Gavin, Laurence and Peter, Thank you very much for your helpful comments! I will keep my goal as moderate as possible. For my problem, I have to include SOC. I just found a way to compute the force using wien with SOC (it seems Gerhard is also interested in this), though it takes time

You cannot minimize with any of the canned routines available with -so as the forces are wrong. To my knowledge the "NOSE" option in Wien2k is more than 10 (perhaps 20) years old, and I am not sure it works. I doubt that it has been used for decades. If you want to do MD I suspect that other

I haven't tried MD with min_lapw. The case.finM should be created by the script min_lapw [ http://zeus.theochem.tuwien.ac.at/pipermail/wien/2006-May/007135.html ]. One of the other users might know better, but it looks like your "min_lapw -p -so" command does not look right. I suggest you

As mewntioned before, the -so option is wrong. One cannot calculate forces with SO in wien2k. Maybe you meant: -spfor a spin-polarized calculation. case.finM will be enerated automatically from the forces of a scf-calculation. Using -so you did not calculate forces, MOLD is in

Dear Wien2k users, I am interested in using Mini to run MD. After reading the manual and old mailing list, I could not find a workable example. For instance, the manual has an example for NOSE (case.inM) not for MOLD. In the structure optimization section, all the examples are used for
