When using a bend loss unit d/s of a junction, I assumed that you could use the remote node option to allow the unit to obtain the upstream velocity from a remote node, but this does not seem to work.  When plotting the velocity for the bend loss unit it just shows the constant initial condition velocity rather than a variable one as is shwon when the bend loss unit is directly d/s of a conduit unit.  Although even using this constant velocity it doesn't appear to be calculating the loss correctly as there should be a small loss (approx. 10mm) but it is showing no loss at all (less than 1mm).  Any ideas?

What about using the "Velocity from downstream node" option? Might not be quite what you want, but does it work?

Remote node *should* work as you describe - I'll have a look.

NB The bend loss doesn't calculate a velocity, nor does a junction, which is why it's displayed as constant for that node (shared by junction and bend loss unit; it just retains the initial condition v, but doesn't use it either - as stated, it should be from the remote node)

to clarify the last part of my last sentence, "it should be..." meaning "it should use it..." (as opposed to output it)
