# Software Verification

## Introduction

Software or code verification is the process undertaken by software vendors to detect errors or bugs in their software. The process involves using the software to model a Benchmark Problem which has a known theoretical solution or a numerical solution with sound provenance.

### Verification of a Euler-Beam element in LISA V8.0.0

This software verification study verifies that the beam element in LISA V8.0.0, which is based on Euler-Bernoulli theory, is capable of converging, with mesh refinement, to the theoretical solution for the fundamental frequency when considering a cantilever beam configuration.
