UCNS3Dis an open-source computational solver for compressible flows on unstructured meshes. State-of-the-art high-order methods and their associated benefits can now be implemented for industrial-scale CFD problems due to the flexibility and highly-automated generation offered by unstructured meshes. We present the governing equations of the physical models employed inUCNS3D, and the numerical framework developed for their solution. The code has been designed so that extended to other systems of equations and numerical models is straightforward. The employed methods are validated towards a series of stringent well-established test problems against experimental or analytical solutions, where the full capabilities ofUCNS3Din terms of applications spectrum, robustness, efficiency, and accuracy are demonstrated.Program summaryProgram title:UCNS3D (Unstructured Compressible Flow Solver)CPC Library link to program files:https://doi.org/10.17632/222zh873kh.1Developer's repository link:https://github.com/ucns3d-team/UCNS3DLicensing provisions:GNU General Public License 3Programming language:Fortran2008Nature of problem:UCNS3D is intended for the simulation of compressible flows in 2D and 3D unstructured meshes, by employing high-resolution, high-order methods capable of providing physically meaningful results in a computational efficient manner.
