Snip access cellset data

Jump to: navigation, search

It would be nice to access data in a cell set like this:

 
filter[cellSet]=filterID;

to set the value of filter for all the cells in the cellSet to filterID, but unfortunately that's not possible.

The way to do this is:

 
cellSet filterSet(mesh,filterName,IOobject::MUST_READ,IOobject::NO_WRITE);
 
for(cellSet::iterator cell=filterSet.begin();cell!=filterSet.end();cell++)
filter[cell.key()]=filterID;

This can be applied to cellSets too.
