How to remove interlayer water?

Hi
I modeling the structure with interlayer water. First build the model with tow layer after this adsorb the water with the adsorption modules.
I need to remove the interlayer water under the environmental situation (simulating evaporation of water). 
Also, I need to emit the interlayer water under the pressure.
And then calculate mechanical properties.

How can I doremove water?
best regards
