CHAM Your Gateway to CFD Success


PHOENICS, which is owned and developed by CHAM, is a powerful multi-purpose Computational Fluid Dynamics (CFD) software package.

PHOENICS provides an accurate, reliable, cost-effective, and easy-to-use tool to simulate a range of processes involving fluid flow, heat or mass transfer, chemical reaction and/or combustion in engineering equipment and the environment. With the longest history of validation and a large user base, it is not surprising that PHOENICS has a proven track record in nearly every branch of science and engineering in which fluid flow plays a key role. Many organisations large and small are using PHOENICS to sharpen their competitive edge in the research and development of products and processes involving fluid flow and heat transfer.
