Good afternoon all,

I am using PyFR to run a DNS simulation of a wall-jet and I have a couple of question about the soln-plugins from it.

- Could `soln-plugin-fluidforce-name` integrate the shear stress at the wall for every step?
- What is the difference between `soln-plugin-dtstats` and `soln-plugin-pseudo-stats`
- What information would the soln-plugin-sampler give me?
- Would it be possible to calculate a fluctuation velocity field using the data provided from `soln-plugin-tavg` or there is a better method to do it?

Thank you for your time and help,
