[Trilinos-Users] Sundance and Tpetra

[Gennadiy Rishkin]

Hi Kevin,

That's excellent. It'll be a brilliant extension to Sundance and (selfishly)
very useful to me.

My application's a reaction-diffusion system coupled with continuum
mechanics equations modeling the electrical wave propagation and mechanical
contraction of the heart.

Many thanks,

Gennadiy
