Hi everyone,

I am modifying the oodles solver to plot dissipation rate from the shear rate. In order to calculate the shear rate I need to call the fluctuating velocity tensor, usually something like u', during the current and from the previous time step. I have been fishing around in several solvers and source code, but have not found the right syntax yet. Can anyone point out what the syntax is or where I can (likely) find it to
1. call u'
2. call u' (or anything for that matter) from the previous time step

Many thanks in advance!
