Abstract : This users guide details the FANS-3D code model and the procedure of execution of the model. This guide was developed in support of Environmental Security Technology Certification Program (ESTEP) Project ER-201-031. Dr. Hamn-Ching Chen and his students and collaborators developed the FANS-3D code over the past 25 years. Programmers use this general- purpose computational fluid dynamics (CFD) code for solving the NavierStokes equations governing laminar and turbulent flows in body-fitted curvilinear grids. The code employs multi-block overset (chimera) grids, including fully matched, arbitrarily embedded, and/or overlapping grids to facilitate detailed resolution of unsteady laminar and turbulent flows around complex geometries involving arbitrary body motions as well as fluid-structure interactions. Communication between grid components is achieved by Lagrange interpolation at the fringes. The code is fully coupled with the hole-making and donor-finding algorithm, allowing for the relative movement of the grid blocks at each time step for time- domain simulation of fluid-structure interaction problems, including violent free surface motions. The underlying theory of the local-analytic-based discretization (also known as finite analytic based discretization) is briefly presented in this users guide.
