Promethium Tutorials

Run a 650 atom Single Point ωB97/def2-TZVPP DFT

Step 1

After you log into your Promethium account, go to the top navigation bar, click on "Workflows" -> "Single Point Calculation".

Step 2

On the Single Point Calculation page:

  • Add Name for job, e.g. “5xek – 650 atom DFT”.
  • Download an example file (5xek.xyz). 
  • Drag & drop 5xek.xyz file into the "Molecule Files" section in the app.
  • Molecular System -> Set Charge: "-6".
  • Molecular System -> Set Multiplicity: "1".

Step 3

In "Environment" section:

  • Check “Implicit Solvation” to ON, and keep Water default for PCM.

 

Step 4

Set level of theory to ωB97/def2-TZVPP:

  • Level of Theory -> Electronic Structure Method: "ωB97".
  • Level of Theory -> Basis Set to: "def2-TZVPP".

 

Step 5

Set parameters for jobs over 100 atoms to:

  • Parameters -> JK Builder: NumericalJKBuilder.
  • Parameters -> JK Builder: PME Cutoff: 1e-10
  • Parameters -> JK Builder: PME Cutoff for Short-Range Correction: 1e-10
  • Advanced -> XC Grid Scheme: SG0.

 

Step 6

On bottom right, click "Review" and subsequently "Submit".

Expected runtime ~4 hrs.
