UpRes and Velocity

Some of you may not be aware but when you have done a sim with a cached velocity for an upres you can switch velocity caching off when you do the actual upres. You do no need it unless you are either doing another upres on it (unlikely) or want to use the velocity for such things as driving particles and velocity displacement. I very rarely have a need for that. You can do subgrid detail without velocity.
OK shameless plug…( I need to pay my electric and rent !!) You can get a full understanding of TFD from my 13 hour tutorial set and a free 45 minute introduction on my YouTube channel to get you going with the basics
