Example:
: Use the same level of theory (e.g., BP86/TZVP) and a conductor-like screening (ε = ∞) for all molecules. 4. Step 2: Prepare Input for COSMOtherm Create a project folder. Copy all .cosmo files (e.g., water.cosmo , ethanol.cosmo , benzene.cosmo ). 4.1 Create parameter file ( BP_TZVP_C30_1701.ctd example) COSMOtherm comes with pre-parameterized files. Choose based on your DFT level. 4.2 Create mixture definition file ( .inp ) Example: VLE of ethanol + water at 1 bar cosmo-rs tutorial
Input:
$COMPONENTS 1 [BMIM]+.cosmo 2 [PF6]-.cosmo 3 water.cosmo $IONPAIR 1 2 BMIM_PF6 Predict CO₂ solubility in the IL. Use COSMOthermX (GUI) or cosmoquick (Python) to plot σ-profiles. Example: : Use the same level of theory (e
