Dear all

in order to calculate the flux I used to integrate the velocity profile manually.

Is there a way to directly compute it?

thanks

There is no context to your question.

Flux of what?

Steve

momentum flux

Fahim

I still don't know what you're talking about.

If you are using the fix viscosity command to

do Muller-Plathe, then it tallies the momentum

flux. You measure the velocity gradient by using

fix ave/spatial and the ratio gives you viscosity.

The doc page explains it.

thanks Steve

suppose I want to sum over all atoms velocities in a specific direction (e.g. x-component of velocities, vx), then time averaging on the resultant quantity.

Best,

Fahim
