I am trying to use a particle user scalar to add up the steps the particle has taken, according to The DEFINE_DPM_SCALAR_UPDATE example 188.8.131.52 in the user manual. When I try to color the particle tracks by this variable, I get the error: Error: CAR: invalid argument : wrong type [not a pair] Error Object: () What am I doing wrong?

There was a defect in Fluent 18.0 that prevented the plotting of particle user scalars. (This defect may affect earlier releases as well.) It is fixed at V 18.2 and onwards.
