Unicorn swMATH ID: 8542 Software Authors: Hoffman, Johan; Jansson, Johan; Vilela de Abreu, Rodrigo; Degirmenci, Niyazi Cem; Jansson, Niclas; Müller, Kaspar; Nazarov, Murtazo; Spühler, Jeannette Hiromi Description: Unicorn: parallel adaptive finite element simulation of turbulent flow and fluid-structure interaction for deforming domains and complex geometry. We present a framework for adaptive finite element computation of turbulent flow and fluid–structure interaction, with focus on general algorithms that allow for complex geometry and deforming domains. We give basic models and finite element discretization methods, adaptive algorithms and strategies for efficient parallel implementation. To illustrate the capabilities of the computational framework, we show a number of application examples from aerodynamics, aero-acoustics, biomedicine and geophysics. The computational tools are free to download open source as Unicorn, and as a high performance branch of the finite element problem solving environment DOLFIN, both part of the FEniCS project.
