Hello everyone, I wanna compute the motion of particle, the equation of which contains a C_UDSI(c, t, 0). I wonder whether DEFINE_DPM_SOURCE can solve the user-defined particle motion equation and calculate the unknown variable, as DEFINE_SOURCE does. If it does, it seems I need to specify a Number of Scalars in DISCRETE PHASE MODEL panel(define->models->discrete phase model->udf) and give the initial value of the C_UDSI(c, t, 0). Is it right and where to set it up?
