# BLZPACK

## Overview

BLZPACK is identified in the dynamic buckling thesis as an open-source eigenvalue analysis solver based on the Block Lanczos method.

## Role In The Source

The thesis uses BLZPACK for eigenvalue analyses needed in vibration analysis, static buckling analysis, and dynamic buckling analysis workflows.

## Connections

- [[Finite Element Eigenproblem Solvers]] gives the broader numerical context.
- [[Geometric Stiffness Matrix]] appears in the static and dynamic buckling eigenvalue problems where such solvers are needed.
