About
High-order methods have the potential to overcome the current limitations of standard CFD solvers. For this reason, we have been developing and improving our spectral element code for more than 35 years now. It features state-of-the-art, scalable algorithms that are fast and efficient on platforms ranging from laptops to the world’s fastest computers. Applications span a wide range of fields, including fluid flow, thermal convection, combustion and magnetohydrodynamics. Our user community includes hundreds of scientists and engineers in academia, laboratories and industry.
