[aspect-devel] The problem of setting up initial composition

[Nan Zhang]

Hi Wolfgang,

I kind of understand the problem. One thing I want to make sure is if
ASPECT allows only one composition field? For example:
*****************************************
subsection Compositional fields
  set Number of fields = 1
end
*****************************************

When I learn it from the user manual examples, it seems that all cookbook
examples get "set Number of fields =2"?

Thanks!
Nan
