I used ANSYS Workbench (DesignModeler, Meshing then Fluent). There are plenty of tutorials on how to use ANSYS Workbench including DesignModeler, Meshing and Fluent.

done
i find the way...
i change the boundary type into interior in GAMBIT...
and the DPM BC is working..

there's another problem.
when i use the simple model to test, it's ok.
then I try to use my model in fluent,
there's a note by fluent: separate interior zone into 2 zones, and changed the BC type of new face to wall.
after that, split interior zone into 2 coupled faces..
One interior changed into 3 faces....
2 in 3 are interior, the last one is wall..
I'm confused..
