Reply To: Question of SmoothIndicator and AnalyticalIdentity
Hi Bobbie,
all the SmoothIndicator* are (in this particular case) scalar fields that can be used on any lattice to initialize all kinds of variables in your simulation. The AnalyticalIdentity operator is able to perform certain calculations between those fields such as addition, subtraction and multiplication. This is also what you can see in the code of your post.
Hope this helps
Kind regards
Tim
