Dear all,
I am trying to calculate the solvation free energy of an organic molecule in an undefined solvent with SMD.
Following the instructions from the Wiki
"The user can specify a solvent that is not on the list by omitting the solvent keyword and instead introducing user-provided values for the following solvent descriptors:.." , I could set up a calculation , since I know all the descriptors of my solvent.
So, the input looks like this:
cosmo
do_cosmo_smd true
dielec 37.2190
sola 0.0000
solb 0.7400
solc 0.0000
solg 49.5600
solh 0.0000
soln 1.4305
end
These parameters have been taken from the DMF. I wanted to test, if NWChem would give me the same results as by using "solvent dmf" .
NWChem runs fine without any problem.
However, when i look at the output file, I noticed that the program calculates it as an aqueous SMD model and reports:
solvent parameters
solvname_short: h2o
solvname_long: water
dielec: 37.2190
dielecinf: 1.7769
aqueous SMD model solvent descriptors
dielec: 37.2190
sola: 0.0000
It seems that it neglects all other solvents descriptors: solb, solc, solg, solg , and it only reads dielec, sola and soln.
Do you have any idea, how I can properly run the SMD calculation for an unspecified solvent?
Or is there a bug in NWChem ?
Thank you.
Best,
Andreas
