Thanks for the reply, DrAmine!

I use DEFINE_DPM_SCALAR_UPDATE to set the particle velocity that i calculate, but then the particle tracking "solver" will override that, i.e., the velocity value that I calculated is not used to update the particle position, instead, a new velocity is calculated by the particle tracking and used to update the position. So I was wondering if there's a way to make the particle tracking only update the particle position but not its velocity.
