.. class:: infomark

**What it does**

This tool solvates a system prior to a GROMACS simulation. In addition, sodium or chloride ions will be added if necessary to ensure the system is charge-neutral.

_____

.. class:: infomark

**Input**

       - GRO structure file.
       - Topology (TOP) file.

In addition, a water model must be selected - this should be consistent with the one selected previously in the system setup.

_____

        
.. class:: infomark

**Output**

       - GRO structure file.
