Recently, during one of my net searches, I came across this page of RPI, where I learnt about a couple of numerical mechanics software which might be of interest to some of you.

FMDB:

As for the effort toward the scalable engineering simulations on distributed environements, we addressed this challenge by developing a distributed mesh data management infrastructure that satisfies the needs of distributed domain of applications.

Trellis:

Trellis is a software framework developed in C++ to make up a reusable design for software to solve problems in geometrically based numerical mechanics.

Have fun!
