Hello abbas,
rename(int fromM, int toM) will replace one material with another.
It is possible to call the rename function with additional parameters. The different ways to call the function can be found in our user guide or our doxygen documentation.
In this case ( superGeometry.rename( 2,1,{1,1} ) ) the material 2 (boundary) is replaced by 1 (fluid), respecting an offset. Here the offset is 1 in both x- and y-direction.
Best,
Maurus
