Stability Analysis

There are two software packages that are being developed for performing stability analysis of large-scale systems. Both packages are integrated into the Trilinos framework. LOCA is a software library for performing bifurcation analysis of large-scale applications. When implemented with an application code, LOCA enables the tracking of solution branches as a function of system parameters and the direct tracking of bifurcation points. The algorithms are chosen to work for large problems, such as those that arise from discretizations of partial differential equations, and to run on distributed memory parallel machines. Anasazi is an iterative eigensolver package that includes several established and novel algorithms, including a block Krylov-Schur approach.
