rodft and range separated-functional


Clicked A Few Times
Hi All,
Is there any reason why rodft should not work with LRC functionals?
Here is the input which crushes (stops after invoking quadratic convergence)
The analogous input with b3lyp finishes without problems.
Perplexed,
Maria

Is this with 6.1.1 or the latest 6.3?

The implementation of the CAM code always assumed a closed shell case was being run when the ROKS code was invoked. A patch for this problem can be found at:

http://nwchemgit.github.io/index.php/File:Roks.patch.gz

You can apply this patch to the nwchem-6.3 source code using the program by running

  cd nwchem-6.3
gzip -d Roks.patch.gz
patch -p0 < Roks.patch
cd src
make

Let me know if you have any problems.
