Validation of the cuIBM code for NavierStokes equations with immersed
boundary methods
• Anush Krishnan, Lorena A. Barba
Description:
We have developed a Navier-Stokes solver, called cuIBM, to simulate incompressible flows using
immersed boundary methods. This document provides background on the numerical methods
implemented in the cuIBM code framework and evidence of the validation exercise carried out by
the authors. The code provides a growing set of options for flows with immersed boundaries, is
written in C++ and uses GPU hardware via CUDA kernels and calls to the Cusp library. The
validation tests in two-dimensions use an analytical solution (Couette flow) and several
experimental results to contrast with the numerical solutions. The experimental benchmarks include
a lid-driven cavity at Re=100, impulsively started flow around a circular cylinder at low and
moderate Reynolds numbers, cylinder wake flow, and flow over both heaving and flapping airfoils.

The Projects We Started This Year Are Rolling
Smoothly Now
The Open Education Project
Started a few months back, this project now boasts a long list of books and educational materials.
All contents are licensed under CC-BY, enabling smooth sharing of the works. India has around 30
major languages and we have a long way to go before we have a comprehensive collection of
educational materials in all these vernacular languages. However, things are already looking up as
we have started to get content in the regional languages too. We are about to take the project to the
next level by starting a system of publishing original content from authors.
