Re: [Wien] Problem in optical properties

The problem is appearing because you have an empty $SCRATCH variable. During userconfig_lapw, it is recommended to set SCRATCH either to a local scratch directory or to "./" . With this setting opticpara works. However, you set it to " " (blank), and this causes the problem in opticpara,

Are you using the latest version of WIEN2k ? Opticpara was fixed some time ago. If yes, please edit $WIENROOT/opticpara_lapw and insert in the first line-xf (instead of -f) and rerun. Capture the output and send it to my private email together with your optic_1.def file. Somehow it

Hi, The GAP2 code is distributed by Hong Jiang. He has a very nice web-site with lots of details and tutorials. It is free of charge, and can work with spin-orbit. It's main limitation is speed, i.e. the highly accurate GW calculations are very expensive and require massive parallelization

As far as I can test it is NOT broken. It works well if $SCRATCH is set to your working directory, but not if $SCRATCH is set to some local directory. (because lapw2 may not find the case.vector_XX file if lapw1_XX ran on a different node because it was free). This is briefly mentioned in
