nekRS 23.0

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 includ

CalculiX 2.22

CalculiX is a free and open-source finite-element analysis application that uses an input format similar to Abaqus. It has an implicit and explicit solver (CCX) written by Guido Dhondt and a pre- and post-processor (CGX) written by Klaus Wittig.[1] The original software was written for the Linux[2] operating system. Convergent Mechanical has ported the application to the Windows operating system.[3] The pre-processor component of CalculiX can generate grid data for the computational fluid dynam
