Hi Matt, Sorry I have been slow to respond. I've been in meetings all day long since Wednesday. I'll take a look at the problem over the weekend or early next week and let you know what I find. B On 04/03/2014 02:19 AM, Matt Frith wrote: I think I may have found a possible bug with the

Dear All, I think I may have found a possible bug with the stand-alone version of (D) Atoms. If I generate an inp file in atoms, save it and then try and run feff on it later, Atoms crashes without attempting the calculation. However, if I load that same input file in (D)Artemis it will run

Many years back, when FEFF stopped being free, I was told that the decision was not Rehr's but forced by the university. Blame them. It's always easier and more pleasant for us to blame faceless university beauraucrats than scientists anyway :-) I agree that FEFF input is broken. This was,

Some users do have FEFFx (x6l) on their own, so it would be useful to prepare Artemis/Demeter/Larch... for them and provide methods for using higher versions if an executable is present. What does the multipole self-energy do? Is that the thing that requires the dielectric response? As you

As I just mentioned to Matt, this conversation is NOT moot because a significant fraction of users have bought access. I wonder if it would be possible to make some sort of 'crippleware' version of FEFF(6) which ONLY runs from within DemLarchTemis? That might make the UW folks a little more

2013-03-26 Thread Devender
Hi, I ran updater for Demeter 0.9.15. I was using Artemis to calculate paths for Bi L3 in Bi2Te3. I saw now the option of using both (FEFF 6 and FEFF 8 style) for atoms. Previously, I was using only available option of FEFF6 style. When I tried to run atoms selecting FEFF 8, it generated atoms
