Hello,

I heard about ChiMES during the 2022 APS March meeting, and I started to assess DFTB/ChiMES capabilities for organic explosives. Currently, the parameter file provided with DFTB+ seems related to the 2020 study with DFTB mio. However, your most recent study seems related to DFTB 3ob and I would be interested in testing ChiMES related to these parameters. Would you mind sending me the ChiMES paramater file for DFTB+ related to this study (High Accuracy Semi-Empirical Quantum Models Based on a Reduced Training Set)? As written in the paper, I sent an email to request the file.

Thank you,
Xavier Bidault

I just read your JPCL paper and the results are really impressive.

In my group, we use a lot DFTB before DFT in different kind of molecules and materials  
I would be delighted to try it in our systems, which go from proteins and peptides, to organic molecules, crystals, carbon nanomaterials, and COFs. 

best regards, 

Manuel Melle Franco

I forgot to mention, that I put my email as a reply from a previous request as I am asking for the same parameters. 

regards

Hi Manuel,

Thank you for your interest in DFTB/ChIMES! We'll send you the parameters from the JPCL paper shortly. Please let us know how things go.

Best,

Nir

Hi Huy,

 

Can you please send your DFTB/ChIMES parameters from the JPCL paper to Manuel? Thanks.

 

Best,

 

Nir
