[gmx-users] How to calculate the number of salt ions?

[Vivek Raut]

Calculate volume of your system box. Standard concentration of Na+& Cl- is
around 143 mOsmole/liter. With this concentration, calculate no. of ions for
your water box. Then use command genion to add those many atoms to your
system.

  Hi, all:

  To make the simulation under a more natural environment, maybe, some NaCl
molecules are needed to add into water solvent.

  My question is whether this step is necessary? and how many Na and Cl ion
pairs should be added?

  This problem is probably a little silly, but I do wanna know about the
answer!

  Your help will be greatly appreciated!



  Regards
