Hi,

 

In principle this is not a NAMD concern. As far as i know that is impossible to do "on the fly". In the end the wrap command is just to mantain the original for of the cell on the output. If you wat you molecules rejoint you have to post-process the dcd in VMD. the command is something like pbc wrap -all -centersel yourComplex. The you can further repair any weird thing due to crossing the cell with pbc join (I don't remember exactly the command here). Check the pbcTools manual for VMD.

Regards
