Hi all,
Can you explain how this command change only the flow cells into the material number 1 and kepps the boundary cells as 2?

superGeometry.rename( 2,1,{1,1} );

I found this function
void rename(int fromM, int toM);
/// replace one material that fulfills an indicator functor condition with another

so the materials are change from 2 to 1, then what is {1,1};

Thanks
