The Loci-Stream CFD code is a scalable parallel tool for fluid-flow and heat transfer simulations in large scale industrial applications. The code supports fully-unstructured grids containing generalized cells with an arbitrary number of faces, including tetrahedral, pyramidal, prismatic and hexahedral cells. Grid translators are provided to create compatible grid files using grids generated from a variety of public domain and commercial grid generation packages. Volumetric and boundary output data may be extracted for visualization with a variety of post-processing packages, including FieldView, Tecplot and Paraview. Many of the common features found in other standard CFD tools such as ANSYS-Fluent and Star-CCM+ are available. End-users can develop modules to customize existing features or add new features to the code.
