[aspect-devel] building a temperature initial condition

[John Naliboff]

Hi Felipe,

deal.II can certainly handle multiple expressions for a given function 
(https://www.dealii.org/8.4.0/doxygen/deal.II/classFunctionParser.html). 
I think some of the particle routines in ASPECT also allow for multiple 
expressions?

However, if you plan on writing a moderately complicated expression(s) 
perhaps a plugin is more suitable?

Cheers,
John
