I don't follow what you're trying to do with 1)   DPM macros are handled a little differently, so check if you're trying to find a cell value or DPM value. 

2) Are you trying to make a cell porous as something happens? Have you tried making the whole region porous but only set a resistance in some cells? I've no idea how stable that will be, that's something you can report back on.
