Fix EHEX SPCE water vapor

Hi all,
Are there any examples or would you have any advice on using fix EHEX to create a temperature gradient across the domain consisting of water vapor SPC/E molecules? All the examples I see using fix EHEX are performing the operation on liquid water. I am finding that with the low density of water vapor it is common for there to be no molecules within the sink or source region causing the algorithm to fail.
Regards,
Peter

I would simply use sufficiently large source and sink regions. E.g. 1/10 of the whole box.
