wien2k: FERMI ERROR when running `x lapw2 -almd -band`
|
|
------------------------------------------------------
|
|
|
|
In some versions of Wien2k, there is a problem in running `x lapw2 -almd -band`.
|
|
|
|
A hack solution is as follows:
|
|
1) `x lapw1 -band`
|
|
2) edit in2 file: replace 'TOT' with 'QTL', 'TETRA' with 'ROOT'
|
|
3) `x lapw2 -almd -band`
|
|
4) `dmftproj -band` (add the Fermi energy to file, it can be found by running `grep :FER *.scf`)

How do I plot the output of `spaghettis`?
|
|
-----------------------------------------
|
|
|
|
In python, you can do the following for example. You should pass the name of
|
|
the file written out by the spaghettis function. Of course, you should change
|
|
the parameters as desired.
|
|
|
|
.. literalinclude:: plotting_spaghettis.py

x optic does not write a case.pmat file
|
|
---------------------------------------
|
|
|
|
Make sure that you set line 6 to "ON" and put a "1" to the following line.
|
|
The "1" is undocumented in Wien2k, but needed to have `case.pmat` written.
|
|
However, we are working on reading directly the `case.mommat2` file.

No module named pytriqs.*** error when running a script
|
|
-------------------------------------------------------
|
|
|
|
Make sure that have properly build, tested and installed TRIQS and DFTTools
|
|
using, make, make test and make install. Additionally, you should always
|
|
use pytriqs to call your scripts, e.g. pytriqs yourscript.py
|
