Tutorial:CAM

From Diracwiki

In DIRAC, you can calculate with the CAMB3LYP functional using

.DFT
 CAMB3LYP

It is also possible to change the default parameters. The following line will reproduce the above functional:

.DFT
 CAM p:alpha=0.19 p:beta=0.46 p:mu=0.33 x:slater=1 x:becke=1 c:lyp=0.81 c:vwn5=0.19

but it will give you complete freedom over the parameters. Note that for this to work correctly you have to apply the following patch. But as always, please verify your results carefully when changing these parameters.
