For 1) it's a little difficult as the DPM model uses the Lagrangian frame and surface monitors etc are Eulerian (ie attached to the cells). Have a look at the accretion model or Wall film and see if that's what you're after.
2) Yes! If the flow field is steady why are you using transient? Equally, is the flow field truely steady or are your experimental instruments not picking up a transient flow feature?
