How to set Langevin dynamics in DS?

Dear all,

I would like to know that how to set Langevin dynamics in DS? How to setup the fbeta. I always use in Charmm, but when ship to use in DS, I cannot find the option for Langevin. I see only NVT, NPT, and NVE. Nothing in the implicit solvate dynamics too.

Thank you very much for your kind consideration.
