Hello everyone,
I need to do calculation during runtime only on the cells which are ~1cm away from a patch.

So the goal is to create a cellSet/cellZone and then to loop over these cells. The best I found so far to create such a cellSet is this function in topoSet:

Code:
 
// Select based on surface     
surfaceToCell     {         
   file            "name.stl";         
   outsidePoints   ((-99 -99 -59));    // definition of outside         
   includeCut      false;              // cells cut by surface         
   includeInside   false;              // cells not on outside of surf         
   includeOutside  false;              // cells on outside of surf         
   nearDistance    -1;                 // cells with centre near surf                                                 // (set to -1 if not used)        
    curvature       0.9;                // cells within nearDistance                                               // and near surf curvature                                               // (set to -100 if not used)     
}
But I need it more general so I don't have to specify each patch by itself.


Does anybody got an idea how to do this?
