what different between wall and baffle
 
What should be I set blade? I have another sample of moving mesh, they set blade is wall. But in tut 7 (star tutorial) set blade is baffle. what different about it? If I should set blade is baffle, how I call forec when I use posdat subroutine?

Thanks

a baffle is an internal zero thickness feature and can either act as a wall (to reduce mesh complexity for thin features) and can also be porous. Baffles must be attached to two cells, walls can only be used on the exterior of the model and can only be attached to one cell

You know the boundary region and start from there. Ask the support for a updated version of the posdat.f

There is a posdat for doing that on adapco-online but its way old and hasn't been upgraded for 3.2x I got my upgraded copy of the support guys so best contact your local office
