Dear All,
I use worm with a harmonic trap defined in a standard version as in ALPS2.0 paper
with the following addition in <SITETERM>  (for 2D vesion)

K#*n(i)*((x-(L-1)/2)^2+(y-(L-1)/2)^2)

works perfectly.
I tried dwa getting the error message:

cannot evaluate y


Trying the one dimensional version with just K#*n(i)*(x-(L-1)/2)^2

works for both worm and dwa.

any idea why 2D harmonic trap cannot be used with dwa?

All the best  kuba
