[Trilinos-Users] [EXTERNAL] How to use and find examples for PyTrilinos

The best examples of how to use the PyTrilinos python module are via the scripts in the packages/PyTrilinos/example directory. The most confusing thing for someone new like yourself might be the package names and what they do. Epetra is a package that supports data structures for linear algebra. AztecOO is a linear solver package. Focus on scripts that have those package names in the script names.

Another way to dive down into the features available for each class is to use the python docstrings. For example, within python run interactively, you can do

   >>> from PyTrilinos import Epetra
   >>> help(Epetra.CrsMatrix)

or within ipython/jupyter, you can do

   In [1]: from PyTrilinos import Epetra
   In [2]: Epetra.CrsMatrix?

Dear Sir/Madam,

My name is Ricardo Lira. I am a PhD student in Petroleum Engineering at UFPE, Brazil. I my research I leverage from numerical methods for solving PDE's and I am currently exploring the Pytrilinos library.
I was wondering if you could help me out on getting more on how to use this tool. You see I am not a programmer. Therefore I was wondering if you could get some of my questions answered.
For instance, I Want to learn how to use some of the Epetra matrices operations and I am struggling in how to use these features.

I hope you can answer my questions and help me out. I am looking forward to hearing back from you.

Kind regards,

Ricardo Lira
