Good Morning all,
First, thank you very much for the feedback on the structured grid notion applied to libMesh.
I'd like to ask about the indexing of elements in a list. Is there any corespondence between computational and real space? Are elements indexed say x-axis major in the array or is there any such regularity by which some maping can be done between computational and real space?
If the answer lies in the degrees of freedom objects, I am working on understanding those.
Ultimately, what I would like to do is be able to take advantage of the a priori known information about the 'structured' nature of the grid to map a Point to an element index - and that is why I am trying to get some information about the element indexing.
Thank you very much for your help.
