# FAQ

Well, FLEXI offers a powerful framework, which is tailored for high-fidelity time-dependent simulations in HPC environments. And yeah, it’s fun and it’s totally for free!

If you used the FLEXI framework for your fancy simulations, we would be happy to have the following paper cited

• F. Hindenlang, G. J. Gassner, C. Altmann, A. Beck, M. Staudenmaier, and C. Munz, “Explicit discontinuous galerkin methods for unsteady problems,” Computers & fluids, vol. 61, pp. 86-93, 2012.
