Running Nalu-Wind

This section describes the general process of setting up and executing Nalu-Wind, understanding the various input file options available to the user, and how to extract results and analyze them. For the simplest case, Nalu-Wind requires the user to provide a YAML input file with the options that control the run along with a computational mesh in Exodus-II format. More complex setups might require additional files:

• Trilinos MueLu preconditioner configuration in XML format

• ParaView Cataylst input file for in-situ visualizations

• Additional Exodus-II mesh files for solving different physics equation sets on different meshes, or for solution transfer to an input/output mesh.
