Dear hoomd-users Group,

I am currently utilizing the hoomd.md.update.ReversePerturbationFlow for calculating viscosity through the Mueller-Plathe method. My inquiry pertains to the specification of the number of time steps (W) until momentum exchange, as mentioned in the original research papers.

In my current understanding and application, I haven't found a way to directly specify W for measuring viscosity. This specification seems crucial for replicating the procedures outlined in the original literature and for ensuring the accuracy of the viscosity measurements.

Could you please advise if there is a method or parameter within HOOMD-blue that allows for the specification of W during the viscosity measurement process? Any guidance or suggestions for approximating this functionality, if not directly available, would also be greatly appreciated.

Thank you for your time and assistance.

Best regards, Koji Iwase

Koji,

Ludwig Schneider is the original author of the ReversePerturbationFlow code. He may be able to answer your question.

How long should I expect to wait for a response from Schneider regarding my inquiry?
